Vagrant pectoral sandpiper at the waste water site

Last Sunday Mohamed Vall and I visited the waste water site north of the city. We saw heavy passage (see last blog).

I concentrated on the warblers and spent little time on waders.

However I did take photos of just one wader which I thought looked a little different. I then looked at the photo on the camera screen and dismissed the bird as a ruff

I should have trusted my initial instincts.

Thanks are due to Bram Piot in Dakar, Senegal and Marco Thoma for correctly identifying the bird as a pectoral sandpiper having seen one picture on yesterday's blog.

pectoral sandpiper

It has a streaked breast, pale base to the bill and an attenuated tail. There are other features which separate it from a ruff.

As far as I can tell this is only the second record of a pectoral sandpiper in Muaritania. The first one was also near Nouakchott. American vagrants should be very possible given how far Mauritania sticks out into the Atlantic Ocean.

In correspondence, Colin Cross from The Gambia pointed out that the American rarity, solitary sandpiper is a much more common occurence in West Africa than pectoral sandpiper. He also observed that the opposite is the case in Europe.

I can only assume that is because pectoral sandpiper takes a slightly more northerly route back to its breeding range.

Either way I need to be more on my guard for Nearctic vagrants such as American golden plover, solitary sandpiper and buff-breasted sandpiper in the future.

Heavy passage at the waste water site

It had been two weeks since our last visit to the waste water site north of the city. Even then there was noticable passage. Both European bee-eater and European roller were added to my country list.

Last Sunday there was heavy passage. 

female pied flycatcher

I had expected to see pied flycatcher given the large numbers that passed through Nouakchott last autumn. I was right.

male pied flycatcher

Once again there were woodchat shrike present. There have been waves of this species passing though for six weeks now. Very many winter in southern Mauritania and they will be included in those passing through.

woodchat shrike

More common redstart were also observed but whinchat were the first seen in the Noaukchott area this season.


However it was the warbler passage which was the most significant. No few than seven types were observed. The numbers present were probably much higher than observed as we didn't go into the densest areas of trees.

Melodious warbler was probably the least common.

We spent considerable time next to the main body of dumped water. Only three warblers were easily seen there.

willow warbler

Willow warbler were in the very short scrub and on surrounding ground.


Blackcap kept making forays out of a near-by large tree onto exposed dead bushes in the middle of the water. This gave excellent and prolonged views. However I was a little disappointed there were no garden warbler with them. This species has still evaded me in Mauritania.

sedge warbler

There was a third warbler observed over the water. It was sedge warbler.  It appeared to have some sort of damage or moult to its tail but otherwise seemed quite healthy.

Views were extremely good for a species which is often hidden in reeds. It's relative, Aquatic warbler, should also be possible at this site on passage.

Many barn swallow were hawking over the water and at least each of red-rumped swallow and house martin were present.

On the last visit two weeks before a lone European bee-eater was seen. This time there was a lone blue-cheeked bee-eater. This was the first time I or my birding partner, Mohamed Vall, had seen one in Mauritania since December 10th.

blue-cheeked bee-eater

It is easy to find the cleanest parts of the water body which is very contaminated overall. You just need to follow the waders.


Little stint was the most numerous and ruff was arguably the most interesting.

red-billed quelea

Along with the house sparrow and Sudanese golden sparrow, some red-billed quelea ventured out on to the exposed dead bushes. This was arguably the most interesting observation of the day. This is the furthest north I have ever seen them. 

The other most interesting observation were Eurasian golden oriole which were sighted during our walk back to Mohamed Vall's car. This was an addition to my country list. Unfortunately though we caught up with them three times, they evaded the camera each time.

Namaqua dove

The site is very active at the moment. Come the summer the few resident birds such as Namaqua dove, larks and sparrows will probably have it to themselves.

Dar El Barka revisited

A week ago Monday, Mohamed Vall travelled the 800 kilometres back to Nouakchott in one day. It was obviously a long day. Nevertheless we made time for one main stop and we chose Dar el Barka in Brakna and next to the Senegal River.

Before that we were lucky enough to see five chestnut-bellied sandgrouse flying over a farming area at Lexeiba, Gorgol. The sandgrouse truned out to be the last addition to my country list during the trip though Dar El Barka had interest.

There is a semi-circle of wide water at Dar El Barka will doesn't quite link up directly with the Senegal River itself. 

We concentrated our time around this rather than other good looking habitat in the area (i.e the river itself, a dense forest and a waterlogged smaller woodland).

Many birds were seeking cover as it was hot day and we were there at the hottest time of day too.

Hamerkop were plentiful. I suspect they came from the dense forest which we didn't have chance to explore. Most of the time they sought cover.

The near-by dense forest may well be the reason that Vinaceous dove was the most common dove in the area. That in itself is very unusual.

With so much water and with wet grassland at the edges, it was no surprise to see a good scattering of both yellow wagtail and collared pratincole.

water bodies at Dar El Barka

No fewr than three types of bee-eater were present. These were little bee-eater, little green bee-eater and red-throated bee-eater. Like elsewhere in Mauritania no blue-cheeked bee-eater were seen. There is more and more evidence that it is not resident in Mauritania unlike the distribution map's claim in Birds of Western Africa. 

While blue-cheeked bee-eater may return in late spring, as a general point there are many more birds that are described in the maps as resident but look now as if they are only present in the rainy season and also just before and after it.

red-throated bee-eater

Red-throated bee-eater stubbornly refused to leave the shade so I have yet to obtain good photos of this bird.

spur-winged goose

The water was attractive to all four of  most common largest water fowl in South Mauritania: spur-winged goose, Egyptian goose, white-faced whistling duck and knob-billed duck.

We didn't have time to do the small birds justice. However of note were chestnut-bellied sparrow lark in the fields and a pair of pygmy sunbird on a beach seeking to drink.

In the long grass just before we left the water, a greater painted snipe was spotted.

Dar El Barka is a fascinating place. It is also just about possible to include it in a normal  weekend's birding based out of Rosso.

Thick woodland in Guidimakha

A week ago Sunday, having spent all morning and part of the afternoon in Gouraye, we headed back to our lodgings in Selibaby.

We knew we had time for another stop and we noticed that weather had clouded over. Presumably it does this every afternoon in the deepest south of Mauritania ahead of the rainy season.

The first bit of good news is that we sighted a Beaudouin's snake eagle on an electricity pylon, 10 kilometres out of Gouraye. It was instantly recognisable, like a short-toed snake eagle but with a dark brown wash on all parts.

A few kilometres later we arrived at a bridge over an apparently dry river bed. However the woodland next to it looked particularly thick.

This proved to be a very good choice of place to stop.

Gosling's bunting

Under the road bridge were several Gosling's bunting. It is highly probable that they nest there.

A much biggest nest was seen once we got into the woodland. It was a hamerkop's nest.

We soon came across some hamerkop. However a bigger discovery was that there was water in places along the stream's bed. This made the woodland much more interesting.

four hamerkop

The small passerines: red-cheeked cordonbleu, red-billed firefinch, black-headed weaver, red-billed quelea were scattered around the wood but were most easily seen drinking.

Near the water were a small number of western plantain-eater. This was yet another addition to my country list. It is a bird usually assocaited with Savannah which gives you an indication as to how dense and wet this piece of woodland was.

western plantain eater

Yellow-crowned gonolek is another bird only found in the south of the country but not as selectively as the plantain-eaters. 

yellow-crowned gonolek

There was a second edition to my list here too. It was brown babbler. Unfortunately the group evaded my camera though Mohamed Vall got a record shot.


Resident African hoopoe were observed. This is ideal terrain for them.

African grey woodpecker (courtesy of Mohamed Vall)

A pair of African grey woodpecker were not easily scared by us. We had expected to see this species here when we surveyed the woodland before we went inside it. However, what we are beginning to question is why neither of us has seen any other type of woodpecker in the country.

Black-billed wood dove (courtesy of Mohamed Vall)

Another expected bird was black-billed wood dove. Indeed it looks better habitat (wettest and denser) than where we had seen them for the first time near Gouraye.

black bush robin

Of course more common birds of woodland were present such as black bush robin and namaqua dove.

We arrived back in Selibaby in the evening well satisfied.
