Year in review: 2019

As is now a bit of a tradition on these pages, I’m again compiling a review of last year’s main birding events. Senegal’s bird year 2019 was a pretty good one, with the usual decent mix of new discoveries, rare vagrants, scarce migrants, range extensions and new breeding records.

First things first: last year saw the addition of two new species to the country’s avifauna, so rather similar to previous years – on average, there have been two additions per year during 2014-2018. First a Willcock’s Honeyguide in Dindefelo nature reserve found by Nik Borrow and his group in January, then the discovery of a small group of Cuckoo Finches at Kagnout in Casamance, in February by Bruno Bargain, Gabriel Caucal and Adrien de Montaudouin. As predicted back in 2018, both Dindefelo and Casamance are obviously key areas for finding new birds in the country. Both species are known to occur in neighbouring countries so these additions are not too much of a surprise, and will likely show up again in Senegal in coming years. These “firsts” bring the total number of species confirmed to occur in Senegal to 674, with seven additional species listed as requiring confirmation. The full checklist as per IOC taxonomy (v.8.1) may be found here.

Next up, the usual lot of vagrants: from North America, the now annual American Golden Plovers (Palmarin in April, and Yene in December), the country’s fourth Pectoral Sandpiper at Lac Mbeubeusse on 5.10, and a Lesser Yellowlegs wintering at Technopole – apparently the longest stay recorded in Africa (at least 71 days!), and most likely the same bird seen several years in a row now.  Two Laughing Gulls that were present at Technopole in April-May – an adult in breeding plumage and a first-summer bird – were the 6th and 7th records; the immature was also seen at Ngor on 22.5. Also at Technopole were at least two different Franklin’s Gulls, one in January and two in April-May including an adult displaying to other gulls. A Lesser Jacana was found by Vieux Ngom on 16.3 on the Lampsar, while a Spotted Creeper on 17.12 at Kamobeul (Ziguinchor) was another rarely recorded Afro-tropical vagrant. And finally from Europe, a Little Gull – possibly not a true vagrant but rather a very scarce winter visitor – was seen on 8.3 at Ngor, and a European Golden Plover was at Saloulou island (Casamance) on 25.2.

 

Scarce migrants included a few species of ducks that are rarely reported from Senegal, starting with these three Gadwalls found by Simon Cavaillès at Technopole in January, which were probably the same birds as those seen in December 2018 in The Gambia. A Eurasian Wigeon was present at the same time; while the latter is regular in the Djoudj, both ducks were apparently seen for the first time in the Dakar region.

Almost a year later this pair of Ferruginous Ducks on a small dam at Pointe Sarène near Mbour on 24.12 were a real surprise in this location. Apparently they didn’t stick around: earlier today (19.1.20) I had the chance to visit the dam again but no sign of our two Palearctic ducks…

An African Crake found by Miguel Lecoq in a dry river bed at Popenguine NR on 12.7 was highly unusual. The two Short-eared Owls at Technopole in January (with one still here on 11.2) were possibly returning birds from the 2017-18 influx as they roosted in exactly the same location; another bird was found in the Djoudj on 26.12 by Vieux and Frank Rheindt. Perhaps more unexpected was a Marsh Owl that was actively migrating at Ngor on 8.10, coming from the north out at sea, but even more spectacular was the discovery of an Egyptian Nightjar by Frédéric Bacuez on his local patch at Trois-Marigots, on 23.10 (an early date and first in this location); in the Djoudj NP, a somewhat classic location for the species, three birds were seen several times from 23.11 up to mid December at least.

A few Red-footed Boobies were again seen at Ngor: an adult on 3.7 and likely the same bird again on 22.7, then daily from 9-12.8 (with two here on 17.8), and again an imm. seen twice in November. These are the 5th to 7th records, a remarkable presence given that the first record was in October 2016 only! As usual, several Brown Boobies were seen as well but we didn’t get the chance to properly check on the birds at Iles de la Madeleine this past year. Other scarce seabirds seen from Ngor were a Balearic Shearwater (18.11), a Bulwer’s Petrel (5.12), several Leach’s Storm-Petrels (11 & 13.11), and some 30 Barolo’s/Boyd’s Shearwaters that passed through in August and September. A Baltic Gull (fuscus Lesser Black-backed Gull) at Technopole 27.1 was our first record here.

Quite a few birds were reported for the first time from Casamance by Bruno and friends, and several resident forest species that had not been seen in many years were “rediscovered” this past year, such as Black-shouldered Nightjar, Black Sparrowhawk, White-throated and Slender-billed Greenbuls, Flappet Lark, Red-faced and Dorst’s Cisticolas – the online Casamance atlast can be found here. Several Senegal Lapwings were again seen towards the end of the rains, and a Forbes’s Plover at Kagnout on 17.2 was definitely a good record as the species had previously been reported only on a few occasions from the Niokolo-Koba NP.

A Brown-throated (= Plain) Martin feeding over the lagoon at Technopole on 28.4 was a first for Dakar; this species is rarely seen in Senegal it seems. A few Moltoni’s Warblers were reported in autumn including at least one on 20.10 at Mboro, where Miguel also noted several northward range extensions such as Fine-spotted Woodpecker, Grey Kestrel, Splendid Sunbird, and Orange-cheeked Waxbill. The observation of two Mottled Spinetails some 15km south of Potou (Louga region) is the northernmost so far and seems to confirm the presence in this part of the country, following one in the same region in January 2018. A pair of Little Grey Woodpeckers at Lompoul and the discovery of Cricket Warbler in the Gossas area (Diourbel) are also noteworthy as they are just outside known distribution ranges for these two Sahelian species. More significant is the observation of a Long-billed Pipit on the Dande plateau near Dindefelo on 9.2, as this is the first record away from the Djoudj area, raising the possibility that the species is breeding in the vicinity.

Additional good records for the Dakar region included a White-throated Bee-eater on 12.8, a Red-breasted Swallow near Diamniadio on 11.10 and Grasshopper Warblers  at Yene lagoon on 8 & 15.12, as well as at Lac Tanma (Thiès region) on 27.10 – and more surprisingly, one was found aboard a sail boat some “400 Miles South West Of Dakar” on 13.9. Last year we documented oversummering of Yellow-legged and Mediterranean Gulls on the peninsula.

We also continued our modest efforts to survey breeding Black-winged Stilts at several sites in Dakar, Ziguinchor and Saint-Louis; the findings of these should be formally published later this year. The Horus Swift colony was visited on several occasions (Jan.-March and Nov.-Dec.) with further evidence of breeding. A pair of Tawny Eagles at their nest site on a high tension pylon near Ndioum, where they are known since at least 2015, were seen again in December by Frédéric and Jérémy. Yellow-throated Longclaw was found to be breeding at lac Mbeubeusse and probably at lac Rose as well: more on the species in this post.

In July we found several additional pairs of Turati’s Boubou right on the border with Guinea-Bissau, a bit further to the south of the site where Bruno initially found the species, in October 2018 near Ziguinchor. Also in Casamance, breeding was confirmed for Common Buttonquail, Golden-tailed Woodpecker, and a whole range of other species.

Another noteworthy record is that of a group of 113 Eurasian Griffons in the Djoudj NP on 2.11 – apparently the largest flock ever recorded in Senegal! This surely reflects the general increase in numbers of what used to be a rather scarce species it seems – read up more on the status of this vulture in Senegal in this post on Ornithondar.

As usual, a few interesting ring recoveries were obtained, including several returning birds, providing further evidence for site fidelity and local movements between key sites for e.g. Black-tailed Godwits and Ospreys of course, but also for a Eurasian Spoonbill from Spain – more on this in a future post. Gull-billed Tern from the Neufelderkoog colony in northern Germany was also a good recovery, just like the many Sandwich Terns that we managed to read at Technopole in April-May with birds originating from Ireland, the UK, the Netherlands and Italy! Also of note were a French Black-headed Gull, the first colour-ringed Greenshank and wing-tagged Marsh Harrier in our ever-growing database, and last but not least the first recovery of a Croatian-ringed bird in Senegal, an Audouin’s Gull seen at three sites in Dakar in January and February.

During 2019 I was fortunate to continue our regular coverage of Technopole but also for the third consecutive year of seabird migration at Ngor, and managed a few trips further afield: the northern Saloum delta (Simal, Palmarin), three trips to Casamance (January, May, July), the Petite Côte (at long last explored the lagoons at Mbodiene!), the Langue de Barbarie and Trois-Marigots in April, the Djoudj and other parts of the lower Senegal valley (November), and finally Toubacouta in December. Oh and a memorable day trip on a successful quest for the enigmatic Quail-Plover!

Other blog posts this past year covered the status and distribution (and a bit of identification!) of Seebohm’s Wheatear, Iberian Chiffchaff, and Western Square-tailed Drongo.

Another series focused on recent ornithological publications relevant for Senegal, in three parts. I’m not sure how I managed but in the end I was involved in quite a few articles published in 2019: the autumn migration of seabirds at Ngor and the status of Iberian Chiffchaff in West Africa (the latter with Paul Isenmann and Stuart Sharp) in Alauda, the first records of Eurasian Collared Dove and of Turati’s Boubou in Senegal (the latter with Bruno Bargain) published in Malimbus, and finally two papers in the Bulletin of the African Bird Club: a short piece on the hybrid shrike from lac Tanma in 2017 (with Gabriel Caucanas), and a review of the status of the Short-eared Owl in West Africa, following the influx during winter 2017/18.

 

Many thanks to all visiting and (semi-)resident birders who shared their observations through eBird or other channels, particularly Miguel, Frédéric and Bruno. The above review is of course incomplete and probably a bit biased towards the Dakar region: any additions are more than welcome and will be incorporated!

 

 

Virée dans le delta, en images

Pas trop le temps pour écrire en ce moment (trop d’oiseaux à compter au Calao!) je voulais tout de même partager quelques clichés pris lors d’une nouvelle visite au Bas-Delta du fleuve Sénégal, au tout début du mois. En compagnie, bien sûr, du référent local et fin connaisseur de l’avifaune de la région – que dis-je, de la faune tout court –  Frédéric Bacuez. D’abord les environs de Bango et les Trois-Marigots, puis une journée dans le parc national du Djoudj avec Vieux, Miguel et Rosa en plus dans la bande, puis pour terminer une matinée dans la réserve de faune du Ndiael. Pas loin (voire un peu plus) de 200 espèces observées pendant notre long weekend ornitho, tous les détails comme d’hab sur eBird.

Sans plus tarder, voici donc en ordre chronologique une petite série d’images:

… puis dans la même zone, une femelle de Moinelette à front blanc (Black-headed Sparrow-Lark). Les deux espèces de moinelette, en plein dans la période de reproduction, sont cette année bien présentes dans la région et elles sont souvent facilement observables. Notez le plumage plus uniforme et plus clair que la femelle de l’espèce précédente.

 

DesertGreyShrike_Djoudj_20191102_IMG_4839

“Desert” Grey Shrike / Pie-grièche “du desert”, nom qui lui convient tout de même mieux, car après avoir été incluse pendant des années dans le groupe de la Pie-grièche méridionale, la rattacher à la Pie-grièche grise d’Europe centrale et du Nord me semble un peu farfelu. Ici très probablement le taxon elegans.

L’autre Lanius du coin, la PGTR (Pie-grieche à tete rousse / Woodchat Shrike), en pleine mue de la queue. Notez également le contraste de mue entre d’un côté les tertiaires et primaires (très sombres au bord blanc bien marqué), et les secondaires brunes bien usées de l’autre.

Northern Wheatear / Traquet motteux, dans le Djoudj également. Pas eu la chance de tomber sur un Traquet de Seebohm – plutôt restreint à l’extreme-nord apparemment – ni sur une cousine Isabelle, un neveu du Désert ou un oncle Oreillard…

Sans doute ces oiseaux venaient-ils d’y passer la nuit, après la grande traversée du Sahara. Peut-être l’un des plus grands groupes, si ce n’est le plus grand, jamais observé au Sénégal?

 

BarnOwl_Djoudj_20191102_IMG_4864

Autre moment fort de la journée, cette Effraie des clochers (Barn Owl) qui niche dans l’un des miradors du Grand Lac, avec pour le moment trois oeufs déposés à même le sol de l’observatoire. Site de nidification pour le moins original!

Trois-Marigots: Gallinule Galore

A recent early morning visit to the Trois-Marigots area, just outside Saint Louis in the lower Senegal delta, quickly turned into a proper gallinule fest, with dozens – hundreds probably! – of rallidaeMoorhens, African Swamphens, Black Crakes, and even a few of the much hoped for Allen’s Gallinule. No crakes this time round, but all in all a pretty spectacular sight in a great setting. Below are a few images taken during our visit, all but the last one taken from the Tylla digue which crosses the second of the the Trois-Marigots. Vieux and I mainly birded a stretch of just a few hundred meters for the first couple of hours, with new birds showing up all the time.

With habitat like this, what would you expect?

Rails of course, but also African Pygmy-Goose, Purple Heron, Black HeronLittle Bittern, African Fish-Eagle, Marsh Harrier, various Acrocephalus warblers, Winding CisticolaZebra Waxbill, and so on.

Allen’s Gallinule is pretty local in Senegal, being most regularly reported from Djoudj and from Trois-Marigots, though it also occurs in Casamance and probably elsewhere (still waiting for it to show up one day at Technopole!). We saw at least two adults, including one with a bright blue frontal shield. The second bird, pictured below, was somewhat duller but the obvious red eye indicates that it is also in breeding plumage, making it likely that the species breeds here at Trois-Marigots.

And here’s that obligatory Pygmy-Goose picture, which I have to say I was quite pleased with:

This one a bit less so, but nevertheless, always great to get a reasonable picture of a nervous warbler that just would not sit still… While most wintering warblers are long gone by now, there were still quite a few of these Sedge Warblers around, plus several Eurasian Reed Warblers, two Willow Warblers, and just one Bonelli’s Warbler. For the most part these are probably birds from the northern part of their breeding range.

Complete eBird checklist here, plus this one from the now bone-dry savanna between the first (also dry by now) and second marigots: Chestnut-bellied Sandgrouse, Temminck’s Courser, Cut-throat, Pygmy Sunbird, etc. For more on Trois-Marigots and its crakes – including the rarely seen Little Crake – see this post, and of course many other notes by Frederic Bacuez on Ornithondar.

A brief visit to the Lampsar near Makhana village, on the opposite side of the route nationale, paid off with quite a few additional species such as fly-over Glossy Ibises, Collared Pratincoles, several waders including two Little Ringed Plovers, and most notably a small colony of Black-winged Stilts, with at least four birds incubating. There were probably several more, given that some of the nests were relatively well concealed as can be seen on the picture below. Checklist here.

Staying on our swamp theme, here are a few more pictures from the Easter weekend which we spent at Zebrabar at the Langue de Barbarie national park. The Saint Louis STEP (sewage farm) was even more smelly than usual, but as always held some good birds such as this River Prinia and Greater Painted Snipe, two species that were also encountered at Trois-Marigots.

Finally, I should mention that Vieux recently found Senegal’s 6th or 7th Lesser Jacana, more precisely at the Lampsar lodge on March 16th. He’d found the previous one just last summer during a waterbird count near Ross Bethio on July 15th. The species is probably a fairly regular yet scarce visitor to Senegal, but its precise status is yet to be defined. Once again Vieux shows that he’s one of the most skilled – and most active – birders in the country!
