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. A 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!
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!
It’s been a while since Technopole last featured here, mostly for a lack of birds… With water levels now extremely low – the main pond only has a few shallow patches of water left – and as a result bird numbers are very low. Just a few hundred Black-winged Stilts, and Spur-winged Lapwings, 100-200 Slender-billed Gulls, the odd Audouin’s and a few oversummering Black-headed Gulls, a few lone waders here and there, 6-8 Greater Flamingos and that’s about it. Luckily there’s always something to see at Technopole, and even if overall numbers of migrants are low at the moment, there’s always some of the local species for which it’s now breeding season!
But more about the gulls first.
One of the previous winter’s Mediterranean Gulls remained up to 10 June at least but only allowed for a few poor records shots, rather unusually a 2nd summer (rather than 1st summer) bird. Apparently the first June record for Senegal, of what in the past 10-20 years has become a regular winter visitor in small numbers to the Dakar region. The last Yellow-legged Gull (Goéland leucophée) was seen on 2 May, also a rather late date.
Actually I just realised that I hadn’t shared some of the better pictures of the star bird of the spring here: the 2nd c.y. Laughing Gull, which ended up staying from 25 April until 22 May at least. With the exception of the adult bird this spring (which was seen only twice by two lucky Iberian observers 🙂 on 21-23 April), all previous records were one-day-wonders.
And while we’re at it, here’s the stunning adult Franklin’s Gull in breeding plumage, which unfortunately didn’t linger and was seen just once, on 30 April, at fairly long range hence the hazy pictures:
This bird is from the following day, probably the 2nd summer seen several times between 13 April and 2 May:
Several Black-winged Stilts are still on the nest, but breeding success appears to be low (because water levels are too low, making the nests more vulnerable?). Only a handful of little stiltlets are seen on each visit, and hardly any older juvs. are around. Wondering whether those at Lac Rose may be more successful this year…
Greater Painted-Snipe (Rhynchée peinte) may also be breeding as a pair was seen on 23 June and a male two weeks earlier in the same area (past golf club house on edge of lake near the small baobab!).
And this year there are quite a few Little Bitterns around, quite obviously more than in previous years, with sightings including several singing birds and pairs in at least five locations. I guess the number of territories all over the Grande Niaye de Pikine could easily exceed 10-12 pairs/singing males. Here’s a rather poor picture of a pair seen on our most recent visit, just before it flew off:
Little Grebe (Grèbe castagneux) was once again confirmed to be breeding, though later than in previous years: an adult with a still downy juv. (aged 1-2 weeks?) was on the small pond past the golf course on 10 June, in the same site as in previous years. Previous records in central and northern Senegal were during Dec. – April (read up more about the breeding status of Little Grebe in Senegal & Gambia in this paper that we published in Malimbus last year)
Another nice surprise last Sunday (23/6) was the first Diederik Cuckoo (Coucou didric) of the season in these parts of the country: a singing bird flew high over the pond coming from the Pikine side, then was heard again later on in the tree belt near the football field. Almost as good as hearing the first Common Cuckoo in early April, back “home” in Geneva!
We’re almost there! In the end, there’s been quite a lot to catch up on since early May…
This colour-ringed Gull-billed Tern which I think I’ve mentioned before is indeed from the small colony of Neufelderkoog in northern Germany – the only site where the species breeds north of the Mediterranean region – and as it turns out it’s only the second-ever resighting of one of their birds in Africa. The first was that of a first-winter bird seen in February 2017 in Conakry, Guinea. Our bird ended up staying at least 16 days, from 13 – 28 April. It was ringed on 18 July 2017 by Markus Risch (“WRYY”: white-red/yellow-yellow) and was a late or replacement brood, and the bird was among the latest fledglings of all.
This Common Ringed Plover was around for some time in April / early May, ringed in Norway (details yet to be submitted).
Also on the ringing front, we’re still waiting to hear back for some of the 40-50 Sandwich Tern ring readings Miguel and I managed to make this spring. One of the most recent birds, seen on May 1st, was ringed in June 2017 at Hodbarrow RSPB reserve in Cumbria (UK), and was already spotted on 25/11/17 at Kartong in Gambia (4,720 km, 148 days). While 2nd c.y. birds all stay in Africa during their first summer, third calendar-years such as this one may already migrate back to Europe.
Rounding off the overview with the most recent addition to the Technopole list: African Wattled Lapwing (Vanneau du Sénégal), which surprisingly had not been seen so far, at least not as far as I know – seems like the species actively avoids dense urban areas, since they are regular just outside Dakar but obviously a bit of a vagrant here in town. One was seen flying past, calling a few times, on 10 June.
Species number 239!
Let’s see if we can manage to find 240 in the next few weeks.
Another visitor from North America showed up recently at Technopole: a superb adult Laughing Gull (Mouette atricille) was found by Miguel Lecoq and Ignacio Morales over the Easter weekend. First seen on 21.4, it was still present two days later when it was also heard calling. Amazingly, later that same week (25.4), Miguel found an immature (2nd year) in the same place!
Identification is pretty straightforward, the main field characters being nicely visible here: dark grey mantle, almost entirely black outer primaries, narrow white trailing edge to secondaries and tertials, back hood with white “eye lashes”, fairly long dark crimson red bill, and rather long dark red to blackish legs. The young bird is also very distinct and is relatively easy to pick out amongst the numerous other gulls that are present at Technopole at the moment: Slender-billed Gulls mostly, but also Grey-headed Gulls (the immatures of which superficially resemble Laughing Gull), and still some Black-headed, Audouin’s and Lesser Black-backed Gulls (Goeland railler, Mouettes à tête grise et rieuse, Goelands d’Audouin et brun).
Proper rare bird record shot:
This is the fourth American species to be seen in Senegal in less than two weeks, once again highlighting the potential of the country to find vagrant gulls and waders: the overwintering Lesser Yellowlegs (Chevalier à pattes jaunes) was last seen on 8.4, followed by a 2nd year Franklin’s Gull (Mouette de Franklin) on 13.4, the American Golden Plover (Pluvier bronzé) from Palmarin (15.4), and now Larus atricilla. And this is by just a small handful of active observers… just imagine what else there is to be found, if only there were more birders here.
There are just five previous records of Laughing Gull:
- An adult in the Saloum delta on 18.3.85 (Dupuy, A.R. (1985) Sur la présence au Sénégal de Larus atricilla. Alauda 53. Two years earlier, a possible sighting in the same place of a bird apparently paired with Grey-headed Gull, could not be confirmed and should thus be ignored.
- An adult at Guembeul (near Saint-Louis) on 12.1.95 (Yésou P., Triplet P. (1995) La mouette atricille Larus atricilla au Sénégal. Alauda 63)
- A 2nd winter in the Saloum delta on 28.12.05, see picture below (A. Flitti; Recent Reports, Bull. Afr. Bird Club 13)
- One flying past the Ngor seawatch site on 7.10.08 (P. Crouzier, P. J. Dubois, J.-Y. Fremont, E. Rousseau, A. Verneau; Recent Reports, Bull. Afr. Bird Club 16)
- An adult at Saint Louis on 10.1.14; a 2nd winter possibly also present (M. Beevers; Recent Reports, Bull. Afr. Bird Club 21)
Elsewhere on the continent, there are records from Morocco, Mauritania, The Gambia, Guinea-Bissau (first records is yet to be published), and possibly elsewhere – most recently, an imm. photographed at the Bijol Islands in Gambia in December 2018. It’s an annual vagrant to western Europe, even in unexpected locations such as on this lake in the Swiss Alps where an adult overwintered in 2005/2006:
Unlike Franklin’s Gull, which has been recorded in all months except for November, with most records in May, July and August, Laughing Gull is obviously a species that is more to be expected in winter, with all records so far occurring between October and April.
Other good birds found during Miguel’s frequent visits these past few days include two other additions to the Technopole list: Golden Oriole on 25.4 (Loriot d’Europe), and Pallid Swift on 23.4 (Martinet pâle). A late Mediterranean Gull (Mouette mélanocéphale) was also a good record, as was the count of 606 Sanderlings.
The site list now stands at 237 species. Which one will be next?
I wrote the preceding paragraphs yesterday, and since then I’ve been – at long last – back to Technopole, as I was up north last weekend and travelling abroad for work this past week. Well, we got the answer: species number 238 is Plain Martin (also known as Brown-throated Martin; Hirondelle paludicole). We had a single bird feeding over the water – often at close range – along with a couple of Barn Swallows (Hirondelle rustique) and several Little Swifts (Martinet des maisons), nicely showing its features. This is a rarely reported species from Senegal, and as it turns out the first eBird observation for the country! It’s rather patchily distributed throughout West Africa, being more common in Morocco, East Africa, and Southern Africa. Considered a non-breeding visitor to Senegal and Gambia, I could only find six old records from Senegal: Morel & Morel list four, followed by one in Jan. 1992 in the Djoudj and one from Mekhe in August 1992. Last year, Bruno Bargain found several at Kambounda (Sédhiou, Casamance), on 2.12.18, but other than those there do not seem to be any recent observations. Very nice sighting and an unexpected addition to my Senegal list – and a cool lifer for Miguel!
Alas no Laughing Gull this morning, but we did see the Frankin’s Gull again. Also another Pallid Swift, as well as new sightings of a colour-ringed German Gull-billed Tern (Sterne hansel) and a Norwegian Common Ringed Plover (Grand Gravelot), plus now two different Med’ Gulls. Let’s try again on Wednesday morning, who knows maybe the gull will be back. It may actually have been around for a few weeks now, as there was a possible sighting at Technopole on March 30th. It’s quite possible that the adult is hanging out by the harbour or elsewhere in the baie de Hann or even Rufisque, and will show up again at Technopole.
