Turati’s Boubou new to Senegal, and other recent records from Casamance

Last month I was lucky to be able to sneak out to Casamance for a few days, a region I hadn’t visited since May 2017 when I paid a brief visit to Kolda. Together with Bruno Bargain, resident birder in Ziguinchor, we explored several areas and managed to see a good number of interesting birds. But before going through the highlights of our trip, it’s about time we gave a few more details about the discovery of a new species for Senegal: Turati’s Boubou, found last October by Bruno near Ziguinchor. This West African endemic appears to be resident in small numbers in at least one locality, but it’s likely that it is actually well established in a few other forests of Basse-Casamance.

This latest addition to the national list was expected, so not a big surprise – but still significant, given that this species was so far only known to occur in Guinea-Bissau, Guinea and Sierra Leone. Our assumption that it should be present in Casamance was based on the fact that the species is present just across the border in northern Guinea-Bissau, and that suitable habitat exists in Basse-Casamance which up to recently was one of the least well known regions, ornithologically speaking, of Senegal. A member of the Malaconotidae, Turati’s Boubou is not uncommon within its restricted range, but its secretive habits make it difficult to find – something I experienced first-hand last month when trying to catch a glimpse of one of the Ziguinchor birds: impossible! Outside of the breeding season (likely just before and during the rains, i.e. May/June – October) they don’t appear to be very vocal and don’t necessarily respond to playback. We heard at least two birds singing briefly – a typical ghost-like boubou song – and while at one point one bird was calling just a few meters away in dense undergrowth at the edge of a remnant forest patch, it just did not want to show itself. Next time! The only recording I managed to obtain was of this call, which when we first heard it was a perfect match of the call recorded by Ron Demey in western Guinea, assumed to be that of a female (included in Claude Chappuis’s CD set). Bruno so far obtained just a single picture but was lucky to get good views of several birds, including an supposed pair (at least three different birds have been found since the first sighting on October 10th. Update 13.02: here’s a picture taken just this morning by Bruno, after an hour of patiently waiting for the bird to show…

More field work is of course needed to get a better sense of this little known species’ breeding cycle, distribution and population size in Casamance; I certainly hope to be able to contribute to this effort in coming months. So for now, here’s just a picture of the habitat in which these birds were found: note the dense undergrowth in otherwise fairly open, dry forest.

Boubou habitat…

 

Of note is that there is at least one unsubstantiated record of Tropical Boubou in Casamance and as a result the species is often listed – incorrectly in my view – as occurring in Senegal: this sighting may in fact relate to Turati’s Boubou which Tropical resembles fairly closely. Even its vocalisations are extremely similar – Chappuis wrote that “it is barely possible to distinguish the two species acoustically” – so it wouldn’t be surprising were this actually Turati’s.

Another target of my short trip was Western Square-tailed Drongo, aiming to obtain sound recordings of this newly described cryptic species which is now included in the reference list maintained by the International Ornithological Committee (IOC 9.1) as a valid species, Dicrurus occidentalis. More on this discovery in this recent blog post. The latest IOC list, published just last week, also includes another taxonomic change in the Dicruridae that affects the Senegal list: the two subspecies of Fork-tailed Drongo D. adsimilis ranging from west to north-central Africa are now elevated to Glossy-backed Drongo D. divaricatus (Fork-tailed Drongo sensu strictu is found in central, eastern and southern Africa). More on the recent taxonomic revisions in a later post…

Anyway, back to Casamance: thanks to Bruno’s excellent field knowledge, we easily found Western Square-tailed Drongo in two locations, and several decent recordings were obtained. While more material is needed, we hope that these will eventually contribute to further our knowledge of vocal differences between occidentalis and its “sister species” Sharpe’s Drongo D. sharpei. As usual, my recordings can be found here on xeno-canto.

During our 72 hours in the field (16-19.01), we specifically targeted a few sites in atlas squares with no or very few records so far, particularly in the area between Bignona and Tionck-Essil where we spent one night in a campement villageois (more on the Casamance bird atlas further down and in this article). All in all we collected close to 400 records of some 175 species, which just highlights the richness of Basse-Casamance.

Birding from dawn to dusk – brilliant!

In addition to the boubou and drongo, some of the highlights were Spotted Honeyguide (lifer! recording of its distinctive song here), Ovambo Sparrowhawk (poorly known and rarely reported species in Senegal), Woolly-necked Stork (a bird flying in from mangroves near Elana), great views and good recordings of Ahanta Francolin which seems to be far more widespread and less of a forest specialist than field guides suggest. And of course, a range of other typical forest species that in Senegal are largely restricted to this part of the country: Buff-spotted Woodpecker, Piping Hornbill, Grey-hooded Capuchin BabblerGreen Crombec, Green Hylia, Little Greenbul, Guinea TuracoGrey-headed Bristlebill, Puvel’s Illadopsis, Olive Sunbird, etc. (Indicateur tacheté, Epervier de l’Ovampo, Cigogne épiscopale, Francolin de l’Ahanta, Pic tacheté, Calao siffleur, Phyllanthe capucin, Crombec vert, Hylia verte, Bulbul verdâtre, Touraco vert, Bulbul fourmilier, Akalat de Puvel, Souimanga olivâtre).

Obtaining good views – or any views at all for that matter – of these forest specials was often difficult, so I don’t really have any good pictures to share. The two below illustrate quite well how challenging this can be in the forest, especially with my bottom-of-the-range camera:

A few scarce Palearctic migrants were seen, including Booted EagleEuropean Bee-eater, House MartinGrasshopper Warbler – the latter in dense grasses on the edge of dry rice paddies near Ziguinchor, a rare record this far south although the species is probably regular in winter (Aigle botté, Guêpier d’Europe, Hirondelle de fenetre, Locustelle tachetée).

This African Pygmy Goose was one of at least nine birds seen on a pond close to those same extensive rice paddies, where they seem to have bred. Other birds in this area, which we visited late afternoon on my first day in town, included Giant Kingfisher, Purple Heron, Piping Hornbill, Quailfinch, Lanner, Whinchat, and so on (Martin-pêcheur géant, Héron pourpré, Calao siffleur, Astrild-caille, Faucon lanier, Tarier des prés).

Similar habitat often holds pairs of Abyssinian Gound Hornbill which appears to still pretty common in Casamance, allowing me to finally see this impressive bird – by some considered to be one of the ugliest birds roaming our planet, though I beg to differ! – which somehow had managed to elude me so far in Senegal. I’d only ever seen it in Awash NP in the Ethiopian Rift Valley, many years ago… We found a small family group feeding in fields just east of Bignona, and another two birds a few kilometers further along the road to Elana. In the end I saw or heard several birds I hadn’t seen before in Senegal, including 4 lifers, bringing my country list to 507 species by the end of the trip. With the addition of Turati’s Boubou, the national list now stands at 677.

I’d like to highlight once again the fabulous work that Bruno and colleagues from the APALIS association are doing in Casamance: with very limited means – but with a great deal of passion and perseverance – they are slowly but surely putting together a comprehensive picture of the distribution and abundance of birds across the region, currently covering some 450 species. Not an easy feat considering how remote and inaccessible many parts of this remarkable region of Senegal are; Casamance is arguably the most diverse and in many ways the most pleasant and most exciting part of the country, and I for one certainly wish I were able to spend more time there. The latest APALIS newsletter (in French, available here as a PDF) contains multiple interesting records and new discoveries, such as the first records in nearly 40 years in the region of White-crested Tiger Heron (with a brilliant picture!), Senegal Lapwings (six near Kamobeul on 30.9.18; despite its name this is a real rarity in Senegal!), and Winding Cisticola; the first regional records of Glossy Ibis, Sun Lark, Singing Bush Lark, Brown-throated Martin, Great Reed Warbler, confirmed breeding of White-backed Night-Heron, and much more (Onoré à huppe blanche, Vanneau terne, Cisticole du Nil, Ibis falcinelle, Cochevis modeste, Alouette chanteuse, Hirondelle paludicole, Rousserolle turdoïde, Bihoreau à dos blanc). The most significant records will be included in the next “Recent Reports” of the African Bird Club bulletin, to be published in March.

In addition to the routine atlassing field work, our friends are now embarking on a project to survey some of the main heronries and other water bird colonies, using a drone to take aerial pictures of the colonies located in dense inaccessible mangroves, thus enabling estimates of the number of nests for each species. The association is currently raising funds to finance the purchase and operating costs of the drone, so please chime in, every bit helps! Link to fundraising campaign here. And please consider supporting APALIS by becoming a member, which at just 15 Euros is just a, well, bargain 😉

And of course, if you have the opportunity to visit Casamance, please get in touch so we can make sure that your observations get incorporated into the database; Bruno can offer advice about where to go or which birds to target more specifically. Nearly three times the size of Gambia, with a good range of different habitats represented, there’s something for everyone. Any birder coming to Senegal should definitely consider visiting this region, and more generally try to get off the beaten birding track – forget about Djoudj, Richard Toll, the Saloum or even Wassadou (and yes even Technopole): Casamance is the place to be!

Enfin, un grand merci à Bruno et sa petite famille pour l’accueil à Kantène!

27/1/19, journée folle au Technopole

Il y a des jours comme ça!

Après une sortie déjà bien mémorable en compagnie de Simon le 24/1, lorsque nous observons entre autres des Canards chipeaux et un siffleur – tous deux des nouvelles espèces pour le site que Simon avait trouvées la veille – puis d’un Bécasseau de Temminck, Miguel et moi avons pris le temps de bien fouiller notre local patch dimanche dernier. Arrivés à l’aube sur les lieux, nous sommes repartis cinq heures plus tard avec pas moins de 111 espèces au compteur. Pas mal du tout, si l’on considère qu’une visite typique en hiver apporte généralement 70 à 80 espèces. De plus, la journée a été exceptionnelle aussi bien point de vue quantité – il devait y avoir facilement 4’000 oiseaux au Technopole ce jour-là – qu’en termes de qualité, avec plusieurs oiseaux rares et tout à fait inattendus.

Voici donc, in order of appearance, une sélection d’espèces rencontrées:

  • Tourtelette d’Abyssinie (Black-billed Wood Dove): un juv. dans le coin nord-est du site était une petite surprise, cet oiseau n’ayant apparemment jamais encore été signalé auparavant au Technopole. En même temps, une Tourterelle vineuse (Vinaceous Dove) chantait dans le cordon boisé juste derrière: espèce numéro 233 pour le site!

  • Hibou des marais (Short-eared Owl): on pensait qu’ils ne reviendraient pas un deuxième hiver de suite, mais les revoilà! Au moins deux de ces hiboux qui nous avaient gracié de leur présence l’hiver dernier, alors qu’un afflux important se déroulait en Afrique occidentale, étaient de nouveau présents sur leur dortoir favori dans un groupe d’acacias. Ils y avaient déjà été répéres fin décembre par deux observateurs, donc tout indique qu’ils resteront encore jusqu’à fin mars ou début avril avant de repartir pour nicher en Europe.

 

  • Bécasseau de Temminck (Temminck’s Stint): déjà vu le 24/1, il ne nous a pas fallu beaucoup de temps pour le retrouver dans le même secteur, se nourrissant en compagnie d’autre bécasseaux. Du coup, nous avons pu observer en cette seule matinée tous les Calidris réguliers du pays: Bécasseau maubèche, cocorli, variable, minute et sanderling – pas mal, non? De plus, ce n’est apparemment que la deuxième obs du Temminck au Technopole, la précédente datant de mai 2015. A peine visibles sur la photo, les pattes jaunâtres en combinaison avec le dessus et la poitrine bruns uniformes sont typiques de ce petit bécasseau, trop souvent confondu avec le Minute. Il est ici tout à fait en marge de son aire de répartition régulière, étant bien plus commun en Afrique de l’Est (au Sénégal, il semble hiverner en petit nombre dans le bas-delta notamment).

  • Chevalier à pattes jaunes (Lesser Yellowlegs): alors que je cherchais à mieux observer un pluvier posé parmi les nombreux Grand Gravelots (c’était un argenté…) je vois un chevalier suspect tout près de la piste, se nourrissant activement dans la vase: bec sombre assez court à base légèrement jaune, dessus gris-brun uni, dessous blanc, croupion blanc, et surtout: des pattes jaunes flashant… encore un Tringa flavipes! Serait-ce le même que celui vu l’hiver dernier en février, peut-être même l’oiseau déjà vu en août 2015 et janvier 2016, voire également à Yene en novembre 2017?? En tout cas cette régularité d’observations est intriguante. Comme pour les bécasseaux, nous avons pu observer ce jour tous les chevaliers réguliers au Sénégal, car en plus des habituels des lieux il y avait également deux ou trois Chevaliers arlequins, peu communs ici (Spotted Redshank). En plus de quelques photos relativement nettes pour une fois, on a même réussi à faire un enregistrement de son cri, à écouter ici.

  • Goéland de la Baltique (Baltic Gull): probablement la plus grosse surprise du jour, on a été bien étonnés de voir un adulte on ne peut plus typique de cette sous-espèce nominale du Goéland brun: en comparaison directe avec ce dernier, notre oiseau s’en distinguait nettement par sa taille plus petite (sans doute s’agissait-il d’une femelle), son manteau très sombre, presque noir même, et surtout une projection primaire importante lui conférant un aspect bien plus élégant et plus allongé (un peu comme un Pluvier bronzé comparé au Pluvier argenté!). En vol, les ailes longues et plutôt étroites, avec très peu de blanc au bout des primaires externes, étaient frappantes. Malheureusement après un envol général l’oiseau n’a pas été revu, donc pas de photos à l’appui… Notre première obs au Sénégal, ce taxon est néanmoins connu pour hiverner en effectifs très modestes sur les côtes d’Afrique de l’Ouest (quelques individus? pas sûr même que ce soit un visiteur annuel). Sa présence ici, loin de ses quartiers d’hiver réguliers en Afrique de l’Est et l’ocean indien, a été confirmée grace à quelques lectures de bagues notamment en Gambie. Egalement présent dans le tas de centaines de goélands, au moins un Goéland leucophée (Yellow-legged Gull) de 1er hiver, un individu au manteau très clair.

 

  • Mouette mélanocéphale (Mediterranean Gull): une dizaine d’oiseaux au moins, soit un peu plus que d’habitude. Comme toujours, l’essentiel des effectifs hivernants est composé d’oiseaux de premier hiver. Pas vu d’oiseaux bagués cette fois-ci, mais on vient de me signaler – merci Renaud – que “RV2L” vu l’hiver dernier a été observé il y a tout juste quelques jours au Portugal.

 

  • Canard chipeau (Gadwall): les trois individus trouvés par Simon le 23/1 étaient toujours présents, bien que pas forcément faciles à répérer dans le tas d’anatidés, bien plus compact que quelques jours plus tôt: avec près de 400 Souchets et autant de Sarcelles d’été, cela fait du monde à fouiller… Il s’agit a priori de la première donnée sur la péninsule du Cap-Vert de cet hivernant rare au Sénégal, dont les quelques observations proviennent sauf erreur toutes du bas-delta. On n’a pas vu la femelle de Canard siffleur (Wigeon) cette fois alors qu’elle était assez bien visible les 23-24/1; là aussi il s’agirait d’une première pour le Technopole. Cela fait donc pas moins de 4 ajouts à la liste, et cela en moins d’une semaine.

  • Mouette de Franklin (Franklin’s Gull): encore une obs de ce laridé néarctique! C’est presque devenu banal ici… Un peu loin comme souvent, au repos dans un groupe de Goélands railleurs et Mouette rieuses – bien nombreuses ce jour – j’ai tout de même fait une photo-preuve où l’oiseau, au manteau gris sombre et au capuchon déjà en grande partie noir, est tout juste reconnaissable au milieu du groupe. Entre la photo du Temminck et celle-ci, je ne sais pas laquelle gagnera au concours de la photo la plus pourrie du jour…

Pour le reste, voir notre checklist eBird (merci Miguel!)

Une fois de plus, le Technopole confirme sa position de haut-lieu de l’ornithologie sénégalaise, et de hotspot urbain tout à fait exceptionnel. A voir ce que nous apporteront les prochaines visites!

Year in review: 2018

Just like last year we’re bringing our readers a summary of the past year, reviewing some of the ornithological highlights and discoveries made in Senegal, and recycling some of the pictures and posts that appeared on this website during the past 12 months.

2018 certainly has been a busy year!

We’ll start with the best of all: the discovery of what appears to be an isolated (?) population of Horus Swifts (Martinet horus), some 3,000 km from the nearest known breeding sites and more than 1,600 km from the nearest observations of the species (in northern Ghana). This is probably one of the least expected range extensions uncovered in West Africa in recent years, and something we’re of course quite excited (and rather proud!) of. We found these birds during an epic 4-day trip up north together with Frédéric Bacuez and visiting birder Filip Verroens from Belgium, in early January. Needless to say, the year started off with a bang! Read up the full story here and on Frédéric’s Ornithondar blog (in French). A few of these neat swifts were seen again in February by Frédéric and Daniel Nussbaumer, then in October by Vieux Ngom and myself when some 50 birds were present, again showing signs of local breeding and confirming that these birds are most likely residents here, and just last week a group of visiting American birders saw about 25 birds at Gamadji Sare.

Just a few days earlier, in fact on the first day of the year, we’d already found another species new to Senegal: a Meadow Pipit (Pipit farlouse) at the Yene-Tode lagoon just south of Dakar. This find was a bit more controversial – but probably more expected than those swifts! – in the sense that the pipit shows a fairly unusual plumage for Meadow Pipit and certain characters fit Red-throated Pipit better. However, the unstreaked rump and especially the diagnostic call, which was heard loud & clear several times at close range (but unfortunately not sound-recorded), safely rule out Red-throated Pipit, several of which were present in the area at the same time. Full story, description and many pictures here.

Continuing on the same theme, this past year saw the addition of two more species to the Senegal list: Brown-backed Honeybird – which had already been reported from Wassadou in 2015 but was not documented – and Turati’s Boubou. The former was found by Gabriel Caucanas and friends first at Dindefelo, then at Wassadou and later in the Niokolo-Koba NP (more info here), the latter by resident Casamance birder Bruno Bargain back in October. Both were more or less to be expected and back in July we’d actually predicted that the boubou would be found in Casamance some time soon, given that it is known to occur just across the border in Guinea-Bissau. We’ll write up more about this species in due course, and I hope to soon visit the Ziguinchor area again and see (and record) this little-known species – stay tuned!

With no less than four new species, 2018 definitely boosted the national list which now stands at a respectable 678 species; more on this in a blog piece we wrote on the topic of the national list, which contains a link to a handy spreadsheet with all species seen in Senegal, with English, French and scientific names.

Of course there were also the usual lot of vagrants, mostly Nearctic waders in the Dakar region and especially at Technopole, pretty much as usual!

  • Common Shelduck (Tadorne de Belon): eight in the Djoudj NP on 17/1 were likely the same group as seen in the Diawling just across the border in Mauritania on 30/12, while one at Technopole on 18-19/2/18 confirmed the small influx that occurred during the ‘17/’18 winter: 8th and 9th records!
  • Red-footed Booby (Fou à pieds rouges): one was photographed at Iles de la Madeleine on 26/1 but was only identified later on, while at Ngor up to two adults were seen on several occasions in spring (17/5-22/5, and again on 11 and 22/6) and one was seen twice in autumn (13 & 15/11). These are the 2nd to 4th records for this tropical seabird, which was seen for the first time in October 2016 only.
  • Cinereous (=Black) Vulture (Vautour moine): an imm. west of Fatick on 30/1 and one (different bird) on 26/2 near Sagata, east of Kebemer. These observations coincide with the first records for The Gambia (Feb. ‘18) and Mauritania (Dec. ‘17). We also reported the first record of the species, which had not yet been published so far – more details on the status of this increasing Palearctic vagrant in this piece.
  • American Golden Plover (Pluvier bronzé): one at Technopole on 8 April, followed by two autumn birds, at lac Mbeubeusse on 3/11 and barely a week later a different bird at Pointe Sarene near Nianing on 9-10/11. Read more on this species in Senegal here.
  • European Golden Plover (Pluvier doré): one at Île de Saloulou (Basse Casamance) on 3/1.
  • Lesser Yellowlegs (Chevalier à pattes jaunes): the 8th record was one at Technopole seen by a visiting birder on 8/2 and relocated on 19/2
  • Baird’s Sandpiper (Bécasseau de Baird): the second for Senegal (and first properly documented) was found at Technopole on 25/3 and seen again on 8/4.
  • Buff-breasted Sandpiper (Bécasseau rousset): two birds stayed for a remarkably long time at Technopole, being present from 13/1 (at least one) up to 19/2 at least, then again on 25/3 though this was probably a new bird given that regular visits earlier in the month failed to relocate the two long-stayers; these are the 8th and 9th records.
  • Red-necked Phalarope: (Phalarope à bec étroit): one at Djoudj on 27/2 is the 6th record at least, though it’s quite possible that the species is a more regular visitor than the handful of confirmed records suggest.
  • Franklin’s Gull (Mouette de Franklin): one was seen five times between 20/5 and 20/9 at Technopole; we summarised the status and trends of the species in this post.

 

As usual there are also several African vagrants to be reported, such as Lesser Jacana (Jacana nain) seen on 31/1 and 17/2 (three birds!) at Médina Afia near Manda, Kolda dept., and at Ross Bethio on 15/7 – there are only a handful of previous records, including just one in the north (more on status of this species in this post by Ornithondar). A Pharaoh (= Desert) Eagle-Owl (Grand-duc ascalaphe) filmed at Richard Toll on 20/1 was the third record. Six Senegal Lapwings were found at Kamobeul (Ziguinchor) on 30/9 – apparently the first record in 38 years! Three other species with uncertain status in Senegal – true vagrants or scarce but regular visitors? – were seen in the Niokolo-Koba area: Mottled Swift in February and June; a Forbes’s Plover in June and an Ayres’s Hawk-Eagle on 6/3 (Martinet marbré, Pluvier de Forbes et Aigle d’Ayres) .

A special mention goes to the Kordofan Lark (Alouette du Kordofan) that was photographed at Richard Toll on 1/3 by a group of lucky Belgian birders; this is the first record in several years, and the first pictures to be made available online for this species, prompting us to discuss ID criteria and status in Senegal of this enigmatic Sahel special, see this blog piece co-authored with Simon Cavaillès – by far the most read article on the blog, with more than 500 views since its publication in April.

Several winter visitors were seen in higher than usual numbers or reached areas further south than their usual wintering grounds, such as Short-eared Owl (Hibou des marais; seen in six locations during January-March including a group wintering at Technopole, following the influx in Nov.-Dec.). Other scarce winter visitors included a Little Gull (Mouette pygmée) at Ngor on 12/1, while a group of five Cream-coloured Coursers (Courvite isabelle) near Maleme Hodar (Kaffrine) on 1/3 were possibly the southernmost record ever. Other examples include a Spectacled Warbler (Fauvette à lunettes) near Kaolack on 3/3, a “Desert” Grey Shrike (now surprisingly lumped again with Great rather than Southern Grey Shrike; Pie-grièche grise) in the Boundou reserve on 15/3, and five House Buntings (Bruant du Sahara) at Richard Toll on 1/3.

As usual, a few birds were spotted outside of their regular range in the country: several Pallid Herons on the Cap-Vert peninsula; an African Hawk-Eagle that gave us a bit of an ID challenge at Popenguine (3/11); a Greyish Eagle-Owl photographed at Trois-Marigots on 10/1 (only a couple of previous records from N Senegal, see story on Ornithondar); a Grey Phalarope on 25/2 at Médina Afia (a rare inland record!); a singing Klaas’s Cuckoo near Dagana on 6/10; a Broad-billed Roller at Bango (Saint-Louis) on 31/8; Grey-rumped Swallow at Technopole (7/7); an early Lesser Whitethroat at lake Tanma on 25/9; a Cricket Warbler near Gueuol (north of Kébémer) on 21/11 (Aigle fascié, Grand-duc du Sahel, Phalarope à bec large, Coucou de Klaas, Rolle violet, Hirondelle à croupion gris, Fauvette babillarde, Prinia à front écailleux). In the Djoudj, a Brown Snake-Eagle was reported on 5/12. Familiar Chat and Green Turaco were reported from the Niokolo-Koba NP for the first time, where further observations of Mali Firefinch were made (Traquet familier, Turaco vert, Amarante du Koulikoro). Several species were found for the first time in Casamance, including Glossy Ibis, Singing Bushlark, Plain Martin, Great Reed Warbler – details will follow shortly on this website (Ibis falcinelle, Alouette chanteuse, Hirondelle paludicole, Rousserolle turdoïde). Away from the better known wintering grounds in the north of the country, an Iberian Chiffchaff (Pouillot ibérique) was singing at Wassadou on 25/2, and the Technopole bird found on 31/12/17 continued its presence until 7/1 at least.

New breeding records include what appears to be the first confirmed breeding for the Dakar region of Little Tern in June at Lac Rose with at least 14 nests; in the same location we found a nest of Plain-backed Pipit, while a Quailfinch at lac Mbeubeusse on 18/11 suggests that the species may be breeding in the niayes region (Sterne naine, Pipit à dos uniAstrild-caille). Successful breeding of White-backed Night-Herons (Bihoreau à dos blanc) was confirmed in two locations in Casamance and breeding is also likely along the Gambia river at Wassadou where Pel’s Fishing Owl (Chouette-pêcheuse de Pel) must also have bred. Black-winged Stilts (Echasse blanche) bred once again at Technopole where low water levels created decent conditions in April-June. And a nice breeding record was that of a female Standard-winged Nightjar found incubating two eggs at Pointe Sarène on 4/8 (Engoulevent à balanciers).

A few unseasonal visitors were noted, e.g. early Marbled Ducks and a Black-necked Grebe near Djoudj on Oct. 6th, Western Olivaceous and Melodious Warblers as well as a Woodchat Shrike and even two European Bee-eaters in June; an adult Sabine’s Gull at Ngor on 30/7 (first July record it seems?), and summer Yellow-legged Gulls at Lac Rose (Sarcelle marbrée, Grèbe à cou noir, Hypolaïs obscure et polyglotte, Pie-grièche à tête rousse, Guêpier d’Europe, Mouette de Sabine, Goéland leucophée). Up north, a White-throated Bee-eater and a Pygmy Sunbird were photographed in January near Saint-Louis (Guêpier à gorge blanche, Souïmanga pygmée).

We also continued our seabird migration monitoring efforts during 2018, both in spring and in autumn. Spring migration was summarised in two posts (covering April and May) but the autumn totals are yet to be published. Highlights included decent numbers of Long-tailed Skua (500!) and Grey Phalaropes (1,256!) seen in August when fairly strong north-westerlies created ideal conditions to see these highly pelagic migrants from the coast; both species saw new day records for West Africa it seems. Other good ones included at least 19 Barolo/Boyd’s Shearwaters in Aug.-Sept., a Sooty Tern on 17/9 and several Bridled Terns, while Great Shearwaters passed through in modest numbers around mid-November (Puffin de Barolo/Macaronésie, Sterne fuligineuse, Sterne bridée, Puffin majeur). A pelagic trip on October 1st yielded reasonable numbers of Wilson’s Storm-Petrels (Océanite de Wilson), some shearwaters and skuas, but no rarities this time round. A visiting birder was lucky to see a White-faced Storm Petrel on 3/12 at Iles de la Madeleine, while an observation of Band-rumped Storm Petrel was reported far offshore off Saint-Louis on 25/9 (Océanites frégate et de Castro).

On the ring recovery front, we managed to read some 100 colour rings, mainly of Audouin’s and Slender-billed Gulls (41 & 19, resp.) but also several Greater Flamingos from Spain, a Common Ringed Plover from Portugal, and the first mentions of Avocet in our database (two birds from Spain) as well as a French Mediterranean Gull (“RV2L”) which appears to be the first recovery of this species from Senegal (Goélands d’Audouin et railleurFlamant rose, Grand Gravelot, Avocette, Mouette mélanocéphale). I now have some 420 ring recoveries in my little database: maybe this year I’ll find time to write up some of the key findings.

A few blog posts on birding sites and other topics were published in 2018, namely the following:

We’ve also been pretty active writing up more formal pieces on birds in Senegal, with several articles published in 2018. This post is actually getting a bit too long so I’ll write about these recent publications in a forthcoming article. For now, go out birding!

Finally, thanks to all our readers for their support and encouragement throughout the year, which has seen a further increase in number of page views (almost 25,000) and website visitors. Oh and do let me know if I forgot anything in the above review, which is just an informal overview – nothing official here!

 

 

Description of a new species of Square-tailed Drongo

It’s not every day that a new bird species is described from West Africa, but thanks to some remarkable detective work by Jérôme Fuchs and colleagues, we now know that the “Square-tailed Drongos” occurring in West African forests should be considered a separate species. The researcher from the French National Museum of Natural History and his co-authors from Guinea, Denmark and the US describe what they named Western Square-Tailed Drongo Dicrurus occidentalis in a paper published earlier this year in the journal Zootaxa: Taxonomic revision of the Square-tailed Drongo species complex (Passeriformes: Dicruridae) with description of a new species from western Africa. The full paper is available on ResearchGate and a nice summary is to be found on this site. The abstract is reproduced below.

In summary, Western Square-tailed Drongo is genetically distinct from its “sister species” Sharpe’s Drongo D. sharpei which occurs further east, but cannot be safely identified in the field. The only morphological differences as per current knowledge are bill shape and size: culmen length, bill width and bill height were found to be sufficiently different from Sharpe’s. The authors provide a detailed description of the holotype, a bird collected by Raymond Pujol and Jean Roché on 18 December 1959 in Sérédou in the  N’zérékoré region of Guinea. According to the authors, Western Square-tailed Drongo and Sharpe’s Drongo diverged about 1.3 million years ago, resulting in substantial genetic divergence (6.7%).

Here’s one of the only pictures I could find online of what should now be considered D. occidentalis, from La Guingette forest near Bobo-Dioulasso in Burkina. There’s also this one in the Macaulay Library of a bird in the hand from central Nigeria in 1981.

And for comparison purposes, here’s one of D. ludwigii from South Africa:

Square-tailed Drongo / Drongo de Ludwig, South Africa (Alan Manson)

 

Western Square-tailed Drongo is known to occur in secondary forest and gallery forest from coastal Guinea to Nigeria, likely as far east as the Niger/Benue River system in Nigeria. It also occurs in Senegal and in nearby Gambia, more precisely in the forests of Basse-Casamance but also in the Dindefelo area where it was recently found. Of note is that the only publicly available sound recording of this taxon is from Dindefelo¹, made by Jean-François Blanc and friends in March 2016 when they found several Square-tailed Drongos on the edge of the Dande plateau (see Blanc et al. 2018. Noteworthy records from Senegal, including the first Freckled Nightjar, ABC Bull. 25 (1), for more details and a photograph of one of the drongos). There are several relevant recordings on Claude Chappuis’s CD set, one from SW Senegal and a few different call types from gallery forests in S Ivory Coast.

More sound recordings are needed to establish the extent of vocal differences between the various taxa within the Square-tailed Drongo “species complex”; it is mentioned in the species account on HBW that there are clear regional differences in vocalisations: in W Africa more muted calls compared with E birds, which have more “ringing” tone – not surprising now that it is clear that these are different species! As is often the case with closely related and morphologically very similar species, the song and calls are often sufficiently different to be useful to safely identify the species. I have some from Mozambique, but now just need to go to Casamance – another good excuse to make it out there¹.

Of course, I was now wondering whether any of the drongos that we saw in February in the Dindefelo forest and along the nearby Gambia river, were Square-tailed rather than Fork-tailed Drongo which is the default species throughout… but at least on the picture below Fork-tailed can be confirmed.

The “new” species also occurs further east, creeping into SW Mali and S Burkina Faso where some decent gallery forest still remains. In this respect, the distribution map in the paper isn’t very accurate and slightly misleading as it doesn’t include these two countries, and the range shown for Senegal is way too large. Hopefully the precise distribution, both in Senegal and elsewhere in West Africa, will be further refined in coming years.

Abstract:

We describe a new species of drongo in the Square-tailed Drongo (Dicrurus ludwigii) complex using a combination of biometric and genetic data. The new species differs from previously described taxa in the Square-tailed Drongo complex by possessing a significantly heavier bill and via substantial genetic divergence (6.7%) from its sister-species D. sharpei. The new species is distributed across the gallery forests of coastal Guinea, extending to the Niger and Benue Rivers of Nigeria. We suspect that this taxon was overlooked by previous avian systematists because they either lacked comparative material from western Africa or because the key diagnostic morphological character (bill characteristics) was not measured. We provide an updated taxonomy of the Square-tailed Drongo species complex.

 

¹ Update 2.1.19: in mid-January I managed to sneak out to Casamance for a few days, where I obtained several decent recordings of these drongos, now available on xeno-canto. I also managed a couple of decent pictures, one of which can be found here.

 

 

An Audio Guide to the Birds of Senegal / Un guide audio des oiseaux du Sénégal

Introducing what will hopefully be a useful resource to some readers out there and more generally for birders visiting Senegal or The Gambia!

Until recently, the only comprehensive sets of sound recordings of West African birds were limited to CD collections that are only available commercially, often at a high price – and some are no longer for sale. The most comprehensive of these is the African bird sounds CD set by sound recorder pioneer Claude Chappuis, published nearly 20 years ago accompanied by an extensive booklet, covering 1043 species. As Françoise Dowsett-Lemaire wrote in her extensive review in the African Bird Club Bulletin, this work marks “a landmark in African bioacoustic publications, one that will (and must) be widely used in the field and which will remain unsurpassed for many years to come.”

AfricanBirdSounds_Chappuis

 

The only other relevant audio guide for West Africa published so far is the Bird Song of The Gambia & Senegal CD set produced by Cive Barlow and colleagues in 2002, covering 265 species, but it is no longer available it seems; similar initiatives have covered e.g. East Africa (East African Bird Sounds by Brian Finch) and Zambia (Bob Stjernstedt’s Sounds of Zambian Wildlife).

BirdSongGambiaSenegal_Barlow

 

But who still uses CDs? Digital field guides under the form of Android apps or e-books have made their appearance in recent years, and these often contain a range of sounds for each species – Borrow & Demey’s Birds of Senegal and The Gambia being the most comprehensive, but it’s only available as an Apple Book for iOS devices.

And then there’s xeno-canto.

We’ve often referred to this amazing resource on this blog, but what exactly is xeno-canto? The open-access initiative called the xeno-canto project was established in 2005 by Xeno-canto Foundation, aiming to popularise bird sound recording worldwide, improve accessibility of bird sounds, and increase knowledge of bird sounds. Initially focused on the Neotropics, it soon expanded to all other world regions, including Africa in 2008.

The collection continues to grow substantially: at the time of writing there are 31,275 recordings of 1,974 species for Africa (just over two years ago, in October 2016 there were “just” 19,813 recordings of 1,841 species). Needless to say, much more than any of the audio guides mentioned above, “XC” truly revolutionised the way birders and researchers alike can freely share, access, and use sound recordings. All for free.

XC_Banner

Now for the audio guide:

It’s actually a simple xeno-canto “set”, available through this link:

https://www.xeno-canto.org/set/2242

The selection of 746 sound recordings included in this set cover 450 species, or 66% of the total number recorded in Senegal (677). This is about three quarters of the 600 or so regular species in the country, i.e. excluding vagrants and birds with uncertain status. Vagrants as well as scarce species that typically do not usually call or sing when encountered in Senegal (e.g. Honey Buzzard), or otherwise silent non-breeding visitors (e.g. harriers and other raptors, Palearctic ducks, storks, seabirds), were not included in the set.

There are of course still a few missing species, including several for which there are no recordings at all available on xeno-canto, most notably White-crested Tiger Heron, Beaudouin’s and Brown Snake Eagles, Denham’s Bustard, Cassin’s Honeybird, African Hobby, Sennar Penduline Tit and Crimson Seedcracker. Hopefully these will be added in the near future, in which case I will of course add them to the set. Likewise, for others such as Greater Painted-Snipe (no recordings from Africa on xeno-canto!), Red-headed Quelea and a few other scarce songbirds there are no decent recordings.

The sounds included in this set were for the main part recorded in Senegal or The Gambia, and where not possible I tried to prioritise recordings from neighbouring countries. This is relevant for particular subspecies that show vocal differences between taxa, but also because there may be regional dialects within populations. I chose to include my own recordings where possible, simply because I’m in full control of these and can make sure that sound types, subspecies and other attributes are appropriately registered, and these sounds definitely won’t be deleted.

Do keep in mind that many species have a large repertoire of call types – advertising song, territorial song, subsong, contact call, flight call, warning calls, etc. – and not all are represented in this collection. Also, some species exhibit a great deal of individual variation, and then there’s those that weave in mimicry of other species such as robin-chats. Additional details on behaviour, habitat, background species and other relevant information are provided for many of the recordings.

The recording set is accessible to anyone – no app, no account needed – from any internet -enabled device, while recordings can be downloaded as mp3 files for offline use (but please… take it easy on the “tape-luring”, i.e. attracting birds with playback of their calls or song as a means to see the bird).

Finally, while writing about bird sound recording I can’t not mention The Sound Approach collective which has done so much in recent years to put the importance of bird vocalisations in identification and taxonomy on the forefront, and to firmly establish birders’ interest in sound recording. It’s only after reading their highly acclaimed The Sound Approach to Birding (2006) that I started to better understand bird vocalisations and that I became a fairly active sound “recordist”. Still one of my favourite bird books! Maybe one of these days I’ll write up something about sound recording and sound birding. After all, up to 80% of birdwatching is actually… bird listening!

(Résumé français)

Une compilation de sons d’oiseaux du Sénégal, ce “jeu” xeno-canto  contient des enregistrements de chants et différents types de cris pour une sélection d’espèces, soit 746 enregistrements couvrant 450 espèces. Les visiteurs rares et les migrateurs qui sont généralement silencieux dans les quartiers d’hivernage ne sont pas inclus. Il manque bien sûr plusieurs espèces, mais on espère que des enregistrements pour celles-ci deviennent prochainement disponibles et on les ajoutera alors au jeu. De même, plusieurs espèces existent bien dans la collection xeno-canto mais il n’y a pas actuellement des enregistrements de bonne qualité.

La plupart des enregistrements proviennent du Sénégal ou des pays voisins, et pour l’essentiel il s’agit de mes propres prises de son. A noter que de nombreuses espèces ont un large répertoire de types de sons (chant territorial, “subsong”, cri de contact, cri de vol, cris d’alarme, etc.), et que toutes ne sont pas représentées dans cette collection. En outre, certaines espèces présentent de nombreuses variations individuelles, puis il y a celles qui imitent d’autres espèces telles que les cossyphes. Des détails supplémentaires sur le comportement, l’habitat, les espèces en arrière-plan et d’autres informations pertinentes sont fournis pour de nombreux enregistrements.

Ce jeu d’enregistrements est librement accessible à chacun – pas besoin d’installer d’application, pas besoin de compte utilisateur – et ce depuis n’importe quel appareil avec connexion internet ; les prises de son peuvent être téléchargés en format mp3 pour utilisation hors connexion (mais attention de ne pas abuser de la repasse pour faire sortir les oiseaux !).

Popenguine Raptor Fest (3.11.18)

A visit to Popenguine nature reserve a couple of weeks ago quickly turned into a exciting few hours watching a good variety of raptors – something we’re not much used to in this part of Senegal, where there are few sites that are good for raptors, and most of the time anything else than a Yellow-billed Kite, Osprey or Hooded Vulture will qualify as a good record. Here’s a short overview, in order of appearance!

As always, several Ospreys were to be seen in the reserve; a few birds usually spend the night on the mighty baobabs that dot the Popenguine savanna, and all day long Ospreys can be seen flying around the cliffs or fishing out at sea. Later that same day at the lagoon just south of Toubab Dialaw, we had a good count of some 29 birds, all visible at the same time (Balbuzard). Popenguine of course also had a few Yellow-billed Kites patrolling the area (Milan à bec jaune).

As we were looking for a Common Rock Thrush we’d briefly spotted on a ridge ahead of the footpath, we noticed first an immature Peregrine Falcon flying around, then a European Hobby – the latter a scarce migrant through Senegal so always a good find. Hobby was already seen at Popenguine around the same time last year by Miguel. This time round it looked like it was an actively migrating individual, just like a Common Kestrel that briefly made an appearance shortly after (Faucons pèlerin, hobereau et crécerelle).

Next up was a Marsh Harrier circling in the distance, again probably a bird on its way to wintering grounds further south (Busard des roseaux). I’ve always thought that Popenguine would be a fairly strategic site to look for actively migrating raptors and other birds. Should be interesting to spend a few days here in October-November and February-March!

This Short-toed Eagle on the other hand was probably one of the 2-3 birds that typically spend the winter in the area around Popenguine and Guereo.

Short-toed Eagle / Circaète Jean-le-Blanc

 

Far less expected than the previous species was an African Hawk-Eagle, spotted by Gabriel as it arrived from the north-east and made its way towards the cliffs, at one point circling together with a couple of Ospreys. Initially we weren’t quite sure about its identity and tentatively id’d this bird as a Bonelli’s Eagle, wondering whether a juvenile African Hawk-Eagle could be ruled out, and were a bit puzzled by the very pale appearance of this eagle. Luckily I managed a few record shots, a bit distant and hazy but they should do the trick. The plumage seemed to still be within the variation of worn juvenile Bonelli’s Eagle, but moult should not start until the second year and this bird shows clear moult contrast on with fresh inner primaries growing. Simon was the first to point out, after this post was originally published, that it looked more like African Hawk-Eagle. I eventually sent out the picture for comments, and Dick Forsman kindly responded, confirming that it’s an African Hawk-Eagle: “It is overall lighter below, the juvenile remiges (primaries + secondaries) are too light and too poorly barred below for a juv. Bonelli’s and the replaced inner primary shows just a dark tip without any further barring. Note also the translucent primaries in the images with blue sky, another pro-spilogaster feature.” Thanks Dick! (post updated Dec. 27)

African Hawk-Eagle is reasonable common it seems through the southern half of Senegal, and is a classic sighting e.g. in the Niokolo-Koba area. There are some records from the Saloum delta and even from the middle Senegal valley (as per Morel & Morel and Sauvage & Rodwell), but as far as I know this is the first from the Petite Côte.

I’m still hoping to see Bonelli’s Eagle one day in the Djoudj, Trois-Marigots or elsewhere in the Senegal valley, the only area with more or less regular records in winter (mainly by Frédéric, who year after year has documented the presence of a few birds around Saint Louis and who nicely summarised the current knowledge about this scarce species in West Africa, in this post on Ornithondar).

After we’d reached the top of the cliffs, next up was this Eurasian Griffon which appeared to be actively migrating along the coastline, just like a second bird we’d see a couple of hours later that same morning near Yène.

Barely a few minutes later, Gabriel strikes again with a young Lanner making a brief appearance, just as we were heading back towards the reserve entrance (Faucon lanier). That’s four species of falcons, not bad! In previous years we’ve also had Barbary Falcon near the cliffs, and surely Red-necked Falcon and Grey Kestrel must also occur at least occasionally, while in the wet season it may be possible to encounter African Hobby.

We thought we’d seen pretty much everything when at the last minute a Shikra was seen dashing over the pond (all but dry!), bringing our morning’s total to 11 birds of prey.

Besides all these hooked beaks, as always the nature reserve held quite a few other good bird, such as Gosling’s Bunting, Green-winged Pytillia, Sahel Paradise-WhydahBlue Rock Thrush, and Northern Anteater Chat. In the end we saw two different Common (=Rufous-tailed) Rock Thrushes, a scarce migrant in Senegal, see this post on our first encounter with the species, in February 2016 at… Popenguine! Also a decent flock of Pallid Swifts and a few White-throated Bee-eaters, both pretty good bonus species, while two Pygmy Kingfishers including at least one dark-billed juvenile provided proof that the species is breeding here.

Complete eBird checklist available here.

The bird list for the Popenguine reserve now stands at some 198 species, at a minimum that is: I listed more than 20 other species as being most likely present, but which apparently remain to be confirmed. More on that over here.

Oh and then there were the butterflies – pure magic! Thousands and thousands of butterflies everywhere, especially along the track up the cliffs. With every footstep, small clouds of butterflies would explode, while a constant stream of butterflies was passing by the cliffs. Our visit clearly took place during peak migration season of Painted Lady which were the vast majority, and to a lesser extent some pieridae. And loads of dragonflies! Difficult to capture on camera but if you look carefully at the image below you’ll get a bit of a sense of what I’m trying to explain here.

Northern Senegal after the rains, 3-7 Oct. (Part II)

(continued from our first blog post on this road trip)

After leaving Gamadji Sare behind, we made our way towards Podor with a few stops en route. A nightjar sheltering from the heat (and predators) was flushed by Vieux near forêt de Golette, just minutes after he casually mentioned that those bushes look good for nightjars! We were hoping for one of the rarer species of course, but it turned out to be a Longtailed Nightjar after all, apparently a (young?) bird in very fresh plumage. Also several Knob-billed Ducks here, a Short-toed Eagle, Spotted Thick-knee, Vieillot’s Barbet and so on.

LongtailedNightjar_Podor_20181005_IMG_3769

Long-tailed Nightjar / Engoulevent à longue queue

 

At the scenic Podor quay we had a Marsh Harrier, at least two House Martins and several Red-chested Swallows, some of which were on the opposite side of the river, meaning these were in Mauritanian territory: not insignificant since apparently there aren’t any solid records from our northern neighbour, despite the fact that the species surely must breed on the Mauritanian side of the Senegal delta. Just like in January, we also saw the species further downstream at Dagana. A Montagu’s Harrier and a Black Kite were seen just south of town.

Continuing our westbound journey, we cris-crossed the rice paddies with a few quick stops en route, including an emergency stop near Fanaye Dieri for a raptor which initially puzzled us both, and which turned out to be a young Beaudouin’s Snake-Eagle. This seems to be a (very) scarce wet season visitor to northern Senegal and to southern Mauritania where breeding has been confirmed.

BeaudouinsSnakeEagle_FanayeDieri_20181005_IMG_3787

Beaudouin’s Snake-Eagle / Circaète de Beaudouin

 

At Dagana, the main feature was the constant stream of herons and Long-tailed Cormorants en route to their nigh roost (or in case of the Black-crowned Night-Herons, en route to their nightly feeding grounds). The roost is located in the swamps just east of Dagana, and hosts what must be several thousands of birds. Three Glossy Ibises flew into Mauritania, while Greater Swamp Warblers were singing on the northern river bank. An evening walk produced Nightingale, Barn Owl, Long-tailed Nightjar and more.

 

Day 4: Big Day! Dagana to Saint-Louis via Richard Toll and the lower delta

October 6 happened to be the first “October Big Day” organised by Cornell – more on this eBird page.

Pre-breakfast birding at Bokhol “forest”, then from Dagana to Richard Toll with a couple of stops en route and a visit to the sand quarry where I wanted to check on the Blue-cheeked Bee-eater colony: with some 500 nest holes, probably at least half being active nests, this is an impressive sight. Bonus species here were Northern Anteater Chat, Cricket Warbler, and especially two Standard-winged Nightjars flushed from “broom bushes” which were a real surprise here (but once again both were female type… so alas no standards!). The picture of the quarry shows the habitat of the latter two species in the background. Along the track into the sugar cane plantations, more White-throated Bee-eaters, both bishops, Black-rumped Waxbills, and a fine Pin-tailed Whydah.

But we’re getting ahead of ourselves… at Bokhol, the fields were rather quiet and unlike in Gamadji Sare the previous morning we barely had any northern songbirds. The forest held goodies such as Senegal Batis, more Orphean Warblers, Fork-tailed Drongo, Brubru, a Red-necked Falcon with prey, and a much less expected Klaas’s Cuckoo singing in the distance (appears to be a rare breeder during the wet season in northern Senegal). Full species list here. Another Whinchat and a few other migrants were seen just west of Dagana.

Negotiating our way out of Richard Toll, we continued on to Ross Bethio, more specifically the ponds along the track to the Djoudj NP. This is where Vieux found a Lesser Jacana back in July: only the fifth record for the country (and second in the north), this was an exciting find of course, further highlighting the potential of this site which has received little attention from birders let alone from the National Park authorities – though the good news is that from this year on, the site is included in the monthly waterbird counts conducted by the Djoudj park staff. Full story on the jacana record on Ornithondar, merci Frédéric. During our visit there were loads of herons and whistling ducks, pelicans, several Black Storks and Yellow-billed Storks, more Eurasian Coots, etc. More unusually, we spotted several Marbled Ducks, counting at least 11 of these cool ducks. This appears to be an early date, and a rare record outside the nearby Djoudj NP: almost all observations tend to be from the same area in the national park, at the Grand Lac, typically between December and February. We’d already seen Little Grebes, but now Vieux also spotted a Black-necked Grebe, an adult coming out of its breeding plumage. Again an early date of an uncommon species in Senegal, typically seen in mid-winter in the north. All in all some 78 species were seen here, see eBird checklist.

The long drive through the delta along the Djoudj track was pretty uneventful, and we only stopped briefly at Saint-Louis to watch a group of Black-tailed Godwits which unfortunately were feeding knee-deep in the lagoon, so no colour-rings could be seen. The Saint-Louis sewage works are always a hit, but too often they are ignored by visiting and local birders alike: I was thus keen to show Vieux this site even if we had just about half an hour left. As always, plenty of birds here, best of all being a Great Reed Warbler. We said our goodbyes here, and I continued onto Zebrabar where I’d spend the night, picking up several wader species new for the trip list as well as Brown Babbler on the camp grounds.

Day 5: final bit of birding at Langue de Barbarie et Guembeul lagoons

Up before dawn, I first went to the floodplain south of Guembeul: Savile’s Bustards singing in all directions, a flock of spoonbills of both species frantically feeding, and a good mix of warblers (Melodious, Subalpine, Bonelli’s, Common Whitethroat). The lagoons held Avocets, Black-tailed Godwits (including a ringed bird from northern Germany), lots of Little Stints, Dunlins, Curlew Sandpipers, and so on. A Pallid Swift was seen near Guembeul, and the lagoons near the STEP held a handful of Shovelers and White-faced Whistling-Ducks, including a family with some 11 ducklings, with Little Grebes also showing signs of local breeding.

Time to head back home… uneventful drive, with just a few quick stops between Mouit and Louga whenever I encountered vultures such as this one:
