This is my newly favoured local site given the demise of F-Nord Lake.
It did not disappoint. I observed 35 species during a morning session there. Furthermore there was quality as well as quantity.
I had expected western paleartic migrants and I got them. However there was one Afro-tropical migrant which had arrived from the other direction which stole the show. More about that later.
spur-winged lapwing
I moved out of the avenue of trees towards the main water body a little disheartened. As I walked there, the now usual noisy reception from a number of spur-winged lapwing greeted me.
They make it difficult to approach without scaring the other birds.
black-winged stilt
A few black-winged stilt were dotted about.
common swift
In the early morning there was alot of action above the water. A group of common swift passed through on their way south. They stayed for about an hour. A similar number of barn swallow lingered longer. Just before I left the site two more common swift arrived.
glossy ibis
There were an even larger number of redshank present than the week before. Though I spent my time trying to get a good look at a group of ibis. They all turned out to be glossy ibis but I scrutinised them thoroughly for potential northern bald ibis. The latter bird sometimes wanders into Mauritania from the north.
four glossy ibis
I admit I didn't even notice at the time that one much rarer bird had photobombed my pictures of the four glossy ibis.

It is well out of range. The Senegal River boundary with Senegal is the normal northern extremity of their range though I do know of one previous report in Nouakchott.

The habitat reminds me of the Sabya waste water site in south west Saudi Arabia where my birding colleagues and I proved they bred.
two glossy ibis and a greater painted-snipe
They can wander as witnessed when I found one at Raysut water treatment plant in Salalah, Oman. It almost feels like deja vu.
greenshank
The variety of waders contributed to the large number of species seen. Greenshank were present in deeper water as were common ringed plover on muddy sections.
blue-cheeked bee-eater
Constant sorties from blue-cheeked bee-eater distracted me from my wader watch from time to time.
mixed waders
The picture above shown some of the variety of waders. There is a redshank, two wood sandpiper, two little stint and a dunlin all on one small island.
Having thoroughly searched for more rare waders, I moved back to the trees. This time I started my search at the far eastern end of the avenue. It was more successful than my previous look into trees that day.
western olivaceous warbler
This was the week of the western olivaceous warbler. It was the most common warbler.

There is a very dirty small pond which is surrounded by overhanging bushes along the avenue back towards the car. This was the place where my main variation of warbler types came from this time. There were at least two western olivaceous warbler, a reed warbler, a sedge warbler and a willow warbler there.
Near-by I was scanning the bee-eaters again and one proved to be a European bee-eater. This was only my second in Mauritania and both have been at this site.

I did a second circuit of the main water body. I was happy to get close views of one of the dunlin.

Ruff were also present.
two ruff
One of the glossy ibis finally allowed me very close.

The last wader I saw before I left was a ruff with some remnants of breeding plumage.
