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.
Far less expected than the previous species was a Bonelli’s 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, wondering whether a juvenile African Hawk-Eagle could be ruled out, and 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 seems to still be within the variation of worn juvenile Bonelli’s Eagle, and African Hawk-Eagle can probably be ruled out based on the overall pale appearance, less dense barring on underwing, and absence of a clear dark band on the greater underwing coverts. A bit puzzling is the moult contrast on with fresh inner primaries growing, so maybe it is a second-year bird after all? Opinions welcome!
Yet another addition to my Senegal list – the next species will be number 500 🙂
I was actually expecting to see this species one day in the Djoudj, Trois-Marigots or elsewhere in the lower 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-Whydah, Blue 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.
Quick note to report Senegal’s 12th and 13th American Golden Plovers, a species that is now near-annual here but which always remains a good find.
We found the first of the season last weekend at lac Mbeubeusse (north of Keur Massar) which we visited early afternoon on our way back from a very enjoyable trip to Popenguine – more on that visit in an upcoming post. Both the date (3 November) and the location are rather typical for this wader: out of the 11 previous records, eight are from the Dakar region, and three were obtained between mid-October and mid-December. Paul had already seen a bird in the same location back in March 2013: needless to say that lac Mbeubeusse ought to be visited much more frequently than just a handful of times per year: pretty much every visit is bound to turn up something good. As always we can only speculate about the number of Nearctic vagrants that pass through Senegal every year or that end up spending the winter here…
After spotting what looked like a suspicious Pluvialis plover (= anything but a Grey Plover), based on the fairly contrasted plumage, seemingly long-bodied and long-legged appearance combined with a small-ish bill, we had to wait a while, gradually approaching the lake’s edge, before we could confirm that it was indeed a “Lesser” Golden Plover (= American or Pacific GP). The important primary projection with wing tips reaching well beyond the tail, bronzy rump and lower back, dark-capped head with distinctive pale supercilium and forehead, and most significantly at one point the bird stretched its wings upwards which allowed us to see the grey underwing. Everything else about the bird was pretty standard for a first-year American Golden Plover. Bingo!
To get a sense of the potential of lac Mbeubeusse for waders and other waterbirds, check out our eBird checklist: other good birds here included hundreds of Northern Shovelers and many Garganeys, Ruffs, Little Stints and Common Ringed Plovers, several Curlew Sandpipers and Dunlins, quite a few Audouin’s Gulls, a few terns including all three species of Chlidonias marsh terns, 124 Greater Flamingos, at least one Red-rumped Swallow, etc. etc. All this with Dakar’s giant rubbish tip as a backdrop, spewing black smoke and gradually covering the niaye in a thick layer of waste on its western edge… quite a sad contrast with all the bird life. And definitely not the most idyllic birding hotspot!
Number 13 was found by Mark Finn barely a week later, on Friday Nov. 9th, at one of the lagoons near Pointe Sarène, south of Mbour. As I happened to spend the weekend at nearby Nianing and was planning on visiting Sarène anyway, I went there the following day and easily located the bird, an adult moulting into winter plumage. Unlike the previous bird, it was actively feeding on the shores of a seasonal pond surrounded by pastures and fields, along with several other waders including Ruff, Redshank, Greenshank, Redshank. Wood Sandpiper, Green Sandpiper, Marsh Sandpiper, Turnstone, Common Sandpiper, and Common Snipe. This appears to be the first record along the Petite Côte south of Dakar, at a site that has great potential for shorebirds and other migrants: around Nianing, Sarène and Mbodiène are several seasonal lakes that fill up during the rains, as well as coastal saltwater (or brackish) lagoons as can be seen on the map below. The marker shows where the AGP was feeding on Saturday.
Despite being a bit distant I managed some decent record shots of the bird, but unfortunately my camera was stolen later in the weekend… so these pictures are lost forever to humanity. Not that I would have won any prizes with them. So no more blurred pictures from the field on this blog for a little while.
The Sarène bird looked pretty much like this one, just slightly less black on the chest:
Anyway, as I think we’ve already mentioned in the past, “AGP” is the most frequent Nearctic wader in Senegal and more generally in West Africa, followed by Buff-breasted Sandpiper (nine Senegalese records so far) and Lesser Yellowlegs (eight). See this post for a list of the first eight known AGP records for Senegal. Since then (spring 2017), the following sightings are to be added:
- April-May 2017: an adult and two 2nd c.y. birds from 17.4 – 1.5 at least, with a fourth bird (= technically an additional record) up to 21.5., at Technopole (BP, Theo Peters, Wim Mullié, Miguel Lecoq, Ross Wanless, Justine Dosso)
- 8 April 2018: an adult or 2nd c.y. at Technopole (BP) – photos above and more info here.
- 3 November 2018: one 1st c.y. at lac Mbeubeusse, Dakar (BP, Gabriel Caucanas, Miguel Lecoq, Ross Wanless)
- 9-10 November 2018: one ad. at Sarène, Thiès region (M. Finn et al., BP)
Out of these 12 records, eight are from Dakar (mostly Technopole of course!), just one from the north – the first country record, in 1979 – and two are from Basse-Casamance where the species may well winter, at least occasionally. And six of these records are from just the past four years: one in 2015, four birds in 2017, and now already three birds this year. American Golden Plovers tend to mainly show up in spring (April-May) and in autumn (Oct.-Nov.) as shown in this little chart below; it’s also in spring that they linger the longest: in spring 2017, Technopole saw a continued presence during five weeks, involving at least four different birds. Note that birds that stayed for several days across two months are counted in both months.
A few more hazy pictures from the Mbeubeusse bird:
It’s always a pleasure to read good trip reports by birders who visit Senegal. More and more visitors now report their sightings through eBird or Observation.org, but few go through the effort of writing up their notes – despite best intentions, as I can sadly testify to myself.
Too many birds, not enough time, right?
A small Danish team visited Senegal last November, and I happened to meet them while seawatching at the Calao at the start of their visit, together with guide Carlos who expertly showed them a great deal of excellent birds – and then again towards the tail end when we briefly met up in Toubacouta. I recently received their trip report, one of the few good ones that were published on Senegal recently. There are useful sections on travel arrangements, weather, timing, pets, and resources (many thanks for mentioning this site!). And very importantly, a brief review of key places visited during the trip: Dakar, Trois-Marigots & Djoudj, Richard Toll, Kousmar, Wassadou & the Niokolo-Koba National Park, Toubacouta & Delta du Saloum, and finally Popenguine. Information on key species is provided along with some info on accommodation and access, and almost all are illustrated with pictures showing local habitats. Next up are species lists by site, followed by a comprehensive list of bird and mammal species seen.
Pretty much all the “specials” were found, both up North and in the Saloum and Niokolo-Koba areas. Also a few less expected birds, such as a high count of Stone-Curlews at Richard Toll (90! with 12 more at Trois-Marigots), a slightly out-of-range African Hobby at Trois-Marigots, a couple of Temminck’s Stints, Shining-blue Kingfisher at Wassadou (though apparently it’s quite regular there at the moment), and an Aquatic Warbler seen during the boat tour to the Djoudj pelican colony (they’re present of course, but seeing one is rare!). And a good breeding record of Fulvous Babbler – apparently one of the few confirmed in the country – with a bird on the nest at Richard Toll.
Oh and I almost forgot – the report is stuffed with brilliant pictures including many of the country’s iconic birds, such as this pair of perfect Swallow-tailed Bee-eaters seen near Toubacouta, or the stunning Cricket Warbler from Richard Toll further down (all pictures in this post by Morten Heegaard, Stig Jensen & Jon Lehmberg).
And make sure to read through to the very end, where you’ll find an enjoyable bonus section on the raptor roost at Ile de Kousmar near Kaolack. To quote the authors, “Why a lot more birders aren’t visiting this roost is a total mystery to us, and that some are even spending a night in Kaolack without coming here is simply beyond belief”. I, for one, am ashamed to say I have not made it to Kousmar yet: next winter, sans faute.
The report can be downloaded directly from here (PDF, 5 MB), or from the Cloudbirders site, which contains a number of other good trip reports on Senegal, many of which are from tours combined with Gambia. Many are fairly dull species lists, but among the more recent ones this report by Birdquest from February 2017 (Podor, Dindefelo, Wassadou, Saloum etc.) is worth a read for those planning a trip to Senegal even if it fails to provide any useful information on where to find the most wanted birds (and there are a few errors as well, e.g. Mali Firefinch is not restricted to Kedougou in Senegal, and Marbled Teal is very much a regular visitor to Djoudj). I guess that’s one of the differences between commercial tours that rush from one place to another (imagine spending just a single day in Dindefelo?!) and a bunch of passionate friends who are keen to share their explorations. Dieuredieuf, Morten, Stig & Jon!
And since we’re talking trip reports – a really enjoyable report in very much a different style is this recent one from The Gambia: BIRDBLOG GAMBIA 2018. Woodsmoke…dust…many birds!
“The ironically named Singing Cisticola showed well, but sang very, very badly, however Scimitarbill and Grasshopper Buzzard rebalanced the cool scale”
Proof that birding trip reports don’t have to be boring reads – highly recommend it, I had a real good laugh!
New Year, New Birds! Apparently I found another new species to Senegal – needless to say that this resulted in a rather successful day out birding. Which left me wondering, rather pointlessly, how many country firsts have been found on the first day of the year.
So I first went to Lac Rose, and more specifically the steppe to the NE of the lake as this area had produced a lot of good birds last winter, including three or even four Buff-breasted Sandpipers. I was keen to go back and see if any of the “specials” were around again this winter. One of the first birds I found in the short grass was Greater Short-toed Lark, so things were off to a good start.
As I started walking on the far end of the steppe, I found a very pale wheatear: a textbook Isabelline Wheatear, just like last year in January.
The same area held three Tawny Pipits and a few other birds, though not the hoped-for Temminck’s Coursers.
Towards the end of my visit I came across this Southern Grey Shrike – cool bird, but a bit too flighty to allow for decent pictures.
Also around were several Kittlitz’s Plovers (+ Common Ringed and Kentish on the lake shores), at least four Quailfinches thus confirming the species’ presence in the Niayes IBA, a Black-headed Heron, Vieillot’s Barbet dueting in the distance, and so on.
Next up: the Yène-Tode lagoon. While on my previous visit, barely two weeks earlier (17/12), there was still a good amount of water, by now the lake has all but dried up: just a little trickle here and a small pool there, with just a handful of Black-winged Stilts, Spur-winged Lapwings, a lone Knot, Common Sandpiper and a few other waders. With all the waterbirds gone, I didn’t think I’d see much on this visit, but was soon proved to be very wrong!
Shortly after getting out the car, I located a small flock of Yellow Wagtails feeding on a green patch in what used to be the lagoon just a few weeks earlier. A pipit amidst the wagtails was either going to be a Tree or (more likely) a Red-throated Pipit, so I got the bird in the scope… and was a bit puzzled at first that it didn’t fit either species?! As I approached, it flew off and called a few times, confirming my suspicion: a Meadow Pipit!! It landed a hundred meters or so further in more dense vegetation. I knew this was a good species for the country and wanted to get better views and maybe even a few pictures (I didn’t quite realise it had never been confirmed in Senegal before!), so I went after it, flushed it and again heard the diagnostic hurried hiist-ist-ist-ist flight call. It returned to the original spot, and this time round I got really good views plus a few record shots:
Note the dense streaking on a pale buffy background with streaks clotting together on middle of breast, general lack of warm tones (as would be the case for Tree Pipit), fine bill with diffuse yellowish base, absence of clear pale lines on the mantle (as in Red-throated), the “gentle” expression with fairly pale lores, an indistinct supercilium and narrow-ish submoustachial (what a word!) stripe. The rump was clearly unstreaked (thus ruling out Red-throated Pipit) and while I didn’t manage any good pictures of the hind toe, it did appear quite long and pictures show it to be only moderately curved (ruling out Tree Pipit). These pipits are no easy birds to identify on plumage, but luckily the call is so typical and unlike any other pipit that it allowed for a safe ID while I was watching the bird, and I was lucky to get a few decent shots. A few people have asked me to provide more pictures, so here they are – all are originals without any editing except for cropping.
This bird was obviously in a fresh plumage, and can be aged as a first-winter bird based on the shape and colour of the median coverts: the ‘tooth’ on the dark centre with a clear white tip (Svensson 1992) is quite visible in the pictures.
Meadow Pipit is of course a common species throughout much of Europe, be it as a breeding bird or on passage or as a winter visitor. Its non-breeding range covers western Europe and most of the Mediterranean Basin, extending along the Atlantic coast down to the Canary Islands and Morocco. In Mauritania it is considered to be scarce but regular, reaching as far as the Senegal river delta, more or less as shown on the map below (borrowed from xeno-canto). Surely it must occur at least irregularly in northern Senegal, given its status in nearby Mauritania?
While relocating the Meadow Pipit, I also flushed no less than eight Red-throated Pipits as well as three Common Quails. Two Collared Pratincoles were hanging out by the last puddles; the Marsh Harriers and most of the Ospreys are now gone, but there were still at least two Short-toed Eagles in the area, with another two along the track back to Rufisque. Two Mosque Swallow were also around, while two Zebra Waxbills were rather unexpected, given that they’re not supposed to occur in the Dakar region (see last year’s post on the sighting of a group at Technopole). Tawny Pipit was another addition to the site’s ever-growing list.
Following a very successful morning yesterday at Technopole (Short-eared Owl! Iberian Chiffchaff! Jack Snipe!) I stopped by to have a closer look at the numerous waders, given that yesterday I’d forgotten my telescope at home… Nothing out of the ordinary to report today, just tons of waders, gulls (incl. two Mediterranean Gulls) and lots of Caspian Terns (+150, and now also 27 Greater Flamingos (nine were present yesterday). And I relocated the Iberian Chiffchaff quite easily as it’s singing regularly, and tends to keep to a single bush – more on this in another post.
Oh and happy new year!
Si vous arrivez à déchiffrer les acronymes du titre, alors chapeau! Faute d’un meilleur intitulé pour ce billet, et faute de temps pour écrire un long article sur tout ce qu’on a pu voir ces huit derniers jours, je vous présente ici quelques images prises lors de notre virée dans le Djoudj (le PNOD – parc national des oiseaux du Djoudj), le PN de la Langue de Barbarie (PNLB), la réserve naturelle d’intérêt communautaire de la Somone (RNCIS), et la réserve de Popenguine (RNP). Huit jours a se ressourcer en pleine nature, en agréable compagnie de nos amis Jan, Maria, Kajsa et Marnix venus découvrir le Sénégal – le bonheur.
A commencer par ces Courvites isabelles vus vers le Grand Mirador du PNOD, trouvés par l’excellent guide Vieux Ngom (qui en passant salue toute l’équipe de Genevois!), dans une atmosphère poussiéreuse comme je l’ai rarement vue. Les courvites aussi j’en avais rarement vus, même jamais en fait! Belle coche donc pour commencer les vacances de fin d’année, d’une espèce régulière dans le nord du pays mais qui jusqu’ici m’avait toujours échappée, ici comme ailleurs d’ailleurs.
Voici pour vous faire une idée des conditions météo, qui se résument tout simplement en “vent + froid + sable + poussière”, mais que notre ami d’Ornithondar a très bien expliqué ici. Jamais eu aussi froid au Sénégal… A peine 15 degrés au petit matin… suffisamment peu pour justifier au moins trois couches pour sortir.
Aussi vus dans le Djoudj, dans le désordre: les habituelles Grues couronnées, une ou deux Talèves d’Allen, deux couples d’Anserelles naines, Sarcelles d’hiver, Pie-grièches méridionales, Glaréoles à collier, Tarier d’Afrique, Prinia aquatique, Pygargue vocifère, Fauvette orphée, Alouettes calandrelles, et j’en passe. (Pygmy-Goose, Common Teal, Southern Grey Shrike, Collared Pratincole, African Stonechat, River Prinia, African Fish Eagle, Orphean Warbler, Short-toed Lark). Par contre peu de canards et très mauvaise visibilité sur le Grand Lac, mais Jean-Louis et Maha ont tout de même eu quelques Sarcelles marbrées deux jours plus tard, tout comme l’Outarde arabe et plein d’autres choses (Marbled Teal, Arabian Bustard).
Mais aussi Loup africain, Phacochères à volonté, un Crocodile du Nil, et pas moins de trois Pythons de Seba pour le grand bonheur de tout le monde mais peut-être surtout pour mes amis Jean-Louis et Maha, à peine arrivés au Sénégal.
Passons maintenant au PNLB, ou l’on a passe deux nuits dans notre lodge favori au Senegal: le Zebrabar, niche entre lagunes et ocean, un petit havre de paix qui invite à la relaxation et au far niente… si ce n’était pour tous les oiseaux qu’il y a à découvrir! Même le jour de Noël on ne chôme pas, bien au contraire: en fin de matinee je passe d’abord à la STEP de St. Louis qui comme toujours grouille d’oiseaux, dont le Prinia aquatique, la Rousserolle des canes, plusieurs centaines de Dendrocygnes veufs et fauves tout comme quelques Canards souchets, et une bonne diversité de limicoles (River Prinia, Greater Swamp Warbler, White-faced & Fulvous Whistling-Ducks, Northern Shoveler). Mais surtout, je tombe sur une belle surprise sous la forme d’une Marouette de Baillon que je lève en bordure du sentier entre les deux plans d’eau principaux. Et que j’aurai ensuite le plaisir d’observer et de photographier pendant plus d’une demie heure – quel bonheur! Seulement ma deuxième obs de l’espèce, mais bien meilleure que la première, il y a près de 10 ans aux Pays-Bas.
Au retour de la STEP, brève escale au bord de la piste qui mène au Niokobokk: une Pie-grièche mériodionale (ou doit-on dire Pie-grièche du désert maintenant? voir cet article sur Ornithondar). J’essaierai de revenir sur la question des (sous-)espèces en 2018…
En fin d’après-midi, je pars dans la plaine et la brousse derrière Mouit, là où j’avais eu entre autres Outarde de Savile, Coucou-geai, Oedicnème tacheté et cie. lors de mes précédentes visites. Parcourant la steppe à la recherche de fauvettes (le site me semble idéal pour la Fauvette à lunettes notamment) ou autres pipits, je tombe sur ce Hibou des marais – le sixième au moins depuis début novembre au Sénégal, confirmant ainsi le petit (?) afflux qui a visiblement lieu encore en ce moment. Combien passent inaperçus? J’ai donc une fois de plus dû mettre à jour l’article que j’y avais consacré il y a quelques semaines, avec l’image en plus et quelques obs supplémentaires (dont une de la lagune de Somone).
Ci-dessous le biotope:
Ensuite, après un crochet par Lompoul (Outarde de Savile, Oedicneme tacheté, Petit Moineau, Guêpier d’Orient et j’en passe; Savile’s Bustard, Spotted Thick-knee, Bush Petronia, Little Green Bee-eater), on pose les valises au Dalaal Diam près de la lagune de Somone.
Là, j’en profite pour retourner dans mon coin à Engoulevents à balanciers: rien vu! Ils ont dû repartir sous d’autres cieux. Curieusement, comme en octobre, une Bondrée (Honey Buzzard) me passe par-dessus la tête en filant vers le sud. Vu le plumage c’était un autre individu qu’en octobre, un jeune individu assez roux. Et à la place des Petits-ducs africains, cette fois ce sont au moins deux Chevêchettes perlées (Pearl-spotted Owlet) qui se font entendre de nuit (et parfois de jour) dans le jardin du lodge. Une Cigogne noire (Black Stork) survole le site, un Busard cendré chasse en bordure de la lagune, des centaines de Moineaux dorés du Soudan se mêlent aux Travailleurs a bec rouge et autres tisserins. Et curieusement toujours, je trouve deux Hypolaïs pâles (Eastern Olivaceous Warbler) non loin de la zone où j’avais déjà observé cette espèce peu connue en Sénégambie, en mars 2016. Hiverneraient-ils dans le secteur? Les deux oiseaux évoluaient ensemble et étaient peut-être en couple, à moins qu’il ne s’agisse de deux mâles se disputant un buisson stratégique… Quoiqu’il en soit, l’identification était relativement simple car les deux oiseaux hochaient activement la queue tout en ouvrant les ailes vers le bas, et la structure (notamment le bec plus fin) et les critères du plumage concordent; le chant semblait aussi assez différent de l’Hypolaïs obscure – je dois encore traiter et analyser les quelques prises de son, qui je l’espère ne seront pas trop affectés par le vent.
Point de photos de Popenguine à part un jeune Circaète Jean-le-Blanc (Short-toed Eagle) un peu flou, mais à signaler notamment neuf ou dix Hirondelles de rochers (Crag Martin), deux Monticoles bleus (Blue Rock Thrush), quelques discrets Bruants d’Alexander (Gosling’s Bunting), 4-5 Beaumarquets melba, 2-3 Sporopipes quadrillés (Speckle-fronted Weaver). Visite depuis Guéréo, hier matin 29/12. Au retour, on passe par le Lac Rose, ce qui permet d’ajouter le Goéland d’Audouin à la liste.
Voilà pour ce tour d’horizon, pas si rapide finalement.
Prochaine expédition: la moyenne vallée du fleuve, dans une semaine à peine. Avant cela, on va essayer de profiter des quelques jours de congés restants pour passer au Technopole, les steppes du Lac Rose ou encore la lagune de Yene.
And Yène delivers again!
I went back to our little hotspot on Sunday morning to see what new there was to be found – and whether I could relocate three vagrant ducks that Miguel and colleagues spotted here the previous weekend (my first proper Sengalese twitch!). The lagoon is quite literally shrinking by the day at the moment, so not very much water is left by now – meaning that all waders and other remaining water birds were fairly concentrated in a small-ish area, not all of which is visible from the main viewpoints.
There were tons of waders so it took some time to go through them and count or estimate each species, resulting in the following totals:
- A few hundred Black-winged Stilts (2-300?), still five Avocets
- More than 320 Common Ringed Plovers, again at least two Little Ringed Plovers, but also a couple of Kentish and at least 39 Kittlitz’s Plovers; also several Grey Plovers
- At least 70 Marsh Sandpipers was a pretty high count, even for Senegalese standards (I actually can’t remember ever seeing so many – at one point, about 50 birds were feeding in a single group). Unusually, Marsh Sandpiper was actually the most abundant Tringa wader. Technopole also has more than usual at the moment. There were about 30 Wood Sandpipers, and a handful each of Greenshanks, Redshanks, and Green Sandpipers.
- About 60 Ruff scattered throughout
- 200 Sanderling, 120 Little Stints, ca. 30 Dunlin, one Curlew Sandpiper
- One Turnstone and Bar-tailed Godwit each
- Three Common Snipes
The Pintails, Garganeys, Shovelers and even the White-faced Whistling Ducks seem to have left as the lagoon is probably too shallow now. Instead there are now three Common Shelducks! I didn’t see them at first, but after about half an hour of sifting through the waders, they were suddenly there, actively feeding on the opposite end of the lagoon and seemingly feeling quite at home here! Maybe they’ll end up staying for a few more days or weeks, until the lagoon dries up.
Not a species I thought I would ever see here: despite its name, it’s definitely not common in Senegal! With only six published records it should be considered a real vagrant to the country. The regular winter range of Tadorna tadorna extends along the Moroccan coast, with very small numbers reaching as far south as Mauritania, though apparently the species remains pretty rare even in the Banc d’Arguin NP. Olivier Girard very conveniently summarised the status of the species in West Africa, in a short paper published in the African Bird Club Bulletin in 2009¹. In his overview, he lists 28 records, almost half of which are from Mauritania, and just five from Senegal. One was apparently overlooked despite being published in the well-known “Annotated check-list of birds occurring at the PNOD, 1984-1994” by Rodwell and colleagues, while the location of another record is incorrect.
As far as we know, no other records have been published nor have any been reported to the ABC, on eBird, or on observado.org since Girard’s summary. As such, these should be all previous Shelduck records for Senegal:
- Seven, Delta du Senegal, 27/12/73 (Morel & Morel)
- Two immatures at Djoudj NP, 21/1/74 (Morel & Morel)
- Two on 12-28/2/90 in the Djoudj NP (M. Fouquet in Rodwell et al. 1996)
- 15 in the Djoudj NP, January 1996 (Yesou et al. 1996)
- One in Djoudj NP, Jan. 1997 (Triplet et al. 1997)
- Two on 5/1/97 at Yène-Todé lagoon (= in Dakar region and not “Siné-Saloum” as incorrectly stated by Girard.
And so now, more than 20 years later, we have three first-year birds from 9 to 17/12/17 at Yène-Todé, again! (see also note below for two more records in early 2018)
It’s intriguing that there are so many more old records, given that observer coverage surely must have improved in the last 20-30 years – and that mid-winter waterbird counts are systematically conducted in the Djoudj and most other large wetlands (I really ought to get access to the database with past counts, as there don’t seem to be any published reports available?). What’s more, Shelducks have been on the increase in many parts of their Western European range, so one would logically expect more birds to show up in this part of the world. Maybe milder winters push fewer birds to the southern end of their range, or the populations that have increased are more sedentary than others? In better-watched Mauritania, at least during the first decade of the 21st century, there are just six records listed since 2000, one of which was near the border with Senegal in the Aftout es Saheli in January 2007, while elsewhere in the delta, Shelducks were seen in December 1995 and three times between Nov. ’98 and Jan. ’99: not much!! Three records each are known from Mali, Ghana and Niger, with one from Guinea (January 2006).
Addendum 2/2/18: eight birds were seen at the Grand Lac in the Djoudj NP on 17/1 (C. Ruchet, Y. Menétrey, I. Ndiaye), quite possibly the same group that was sighted on 30/12/17 in the Diawling on the other side of the border. The first for Technopole was on 18-19/2/18 (E. Regala Ruiz, J. Ruiz, BP, G. Caucal, E. Rogeau), confirming the small influx that occurred during the 17/18 winter.
So what else was about? Glossy Ibis is still present (at least 3 ind.), and now no less than 28 European Spoonbills, most of which arrived from the NW and landed in the central part of the lagoon. As usual there were several Osprey and Marsh Harriers, plus an immature Short-toed Eagle hunting around the lake’s edge, a pair of Red-necked Falcons roosting on a tree, and a Common Kestrel (and on 9/12, Miguel & co. had a fine Barbary Falcon).
The flock of gulls and terns held the usual Caspian, Royal, Sandwich and Common Terns, but just a few Audouin’s Gulls, LBBGs, Slender-billed, Grey-headed and Black-headed Gulls this time round.
Just like on my last visit, Red-throated Pipit was present on the lagoon’s edge: I first heard its sharp pssiiiii call in the SE corner, then briefly saw (and heard) what was probably a second bird, a few hundred meters further. Two Tree Pipits were also present.
Other migrant songbirds included Yellow Wagtails of course, plus Northern Wheatear, Subalpine Warbler, Common Whitethroat, Sedge Warbler, and Woodchat Shrike.
All in all, another very enjoyable morning out at Yène!
A Technopole pit-stop on the way back to Dakar resulted in yet more waders, with still some 300 Black-tailed Godwits around (just one ring could be read, as most birds were feeding or resting in deeper water) and lots of other waders. On my previous visit, we managed to read six rings, mostly in this flock of BTGs feeding on land:
The water levels are already quite low and I’d reckon that they are about the same as in April 2017: let’s hope that the site doesn’t completely dry up by the end of the dry season!!
More of a surprise was an adult African Spoonbill (also two Europeans) resting on one of the islets, its deep crimson face just about visible. Surprising, because it’s not a frequent visitor to Technopole, and so far my only records have been in April and May.
A Common Moorhen with a very young chick, confirming local breeding of the species. Other than that, lots of Lesser Black-backed Gulls (+300), a few Audouin’s Gulls, a White-winged Tern feeding among the Black Terns, at least two Knot, lots of Ruff, etc. An adult male Peregrine Falcon may be the same bird that I see almost daily on the Diarama hotel.
