He works for the Libyan Environment General Authority and he is a very good bird watcher.
I think he is a very good photographer too! He took all the photos you see below.
flock of slender billed gull by Ali Berbash
All these pictures were taken on December 12th either at Farwa lagoon or near-by at Zuwarah.
In Tripolitania in winter the gulls are mostly slender billed gull and yellow legged gull (both also found in Cyrenaica), Audouin gull (rare in Cyrenaica) and black backed gull (uncommon in Cyreniaca). Conversely the most common gull in Cyrenaica in winter is black headed gull which is uncommon in Tripolitania.
The first picture above is of slender billed gull which is found all over the Libyan coast. I think this is a beautiful shot.

The picture below is at Zuwarah which is about 20 kilometres east of Farwa. The birds are a mix of Audouin gull and Mediterranean gull.

Caspian tern breed at Farwa and can be seen there in the winter and at near-by Zuwarah. This is probably there southernmost breeding place in the Western Palearctic. Some Caspian tern migrate 1,000s of kilometres but Farwa's birds don't migrate. Its quite possible their numbers are strengthened in winter by migrants.

The final picture is a real mix of gulls and terns. I can see Mediterranean gull and black backed gull and Caspian tern. There are also three lesser crested tern towards the right. (tip you may need to blow up the picture which is constrained by the blog limits).
Gulls and terns
Last year at about the same time I also saw some lingering lesser crested tern. It's seems in mild Octobers and Novembers some linger although I didn't see any when I visited last January. I wonder if the remaining ones in December?
Thanks are due to Ali Berbash for giving me permission to show his photos.
