Hi

All the photos were taken on 19th January at the Abu Dhabi Golf Course.

I have no better pics of the first bird, as this was the most I saw of it over a fustrating period of ten minutes after which it disappeared around the corner of an island.

The first is a Cormorant (Phalacrocorax carbo), the second and third are Slender-billed Gulls (Larus genei), and the last two are European White-fronted Geese (Anser albifrons albifrons).

Care to put an age on the SB Gulls Josh? The plumage looks adult, but the bill colour is 1st winter. I have never seen an adult with such a pale orange-yellow bill.

Yes, 3CY (2nd-winter) would be my guess too.

It could be a 2nd w bird yes, but also a sick adult with some problems ...such birds do not have colourfull bare parts...

We need to see open wing and tail to check PC (primary coverts), secondar., tertials, and rectrices....

Ciao

I have looked at these SB Gull photos again and can't help but think that there is something wrong (not meaning it is sick, or anything like that) with this bird. I have spent a lot of time looking at this species which can occur locally in large numbers in the eastern Algarve, and there is something a bit odd about the structure of bill and head. Or is it just my imagination?

The two photos are of the same bird and I did see it fly. It took off so rapidy that I didn't get a shot but from what I witnessed I doubt it was sick.

Is this also Phalacrocorax carbo? Horrible pic but the light was terrible.

No, its quite typical, nothing wrong... bill shape, as the gonydal, could vary quite visibly even if yet less than in for ex. Yellow-legged, Lesser BB etc... but yet variable, as in any birds and animal (for ex. the Plovers in the other discussions). Some birds have a thicker bill though a bit only, other a slender, other such this a gonys well pronunced, other a bit less (sex, indidvidually etc.).

Sick does not means is not able to flyght, means some sickness as problem with metabolismo, with other internal stuff I can't explain in English sorry...not my lenguage that is Italian :-(

Cheers
