[QUOTE="JANJ, post: 1278130, member: 20722"] Himalaya, I was not specific when I mentioned LBBG.There are graellsii, intermedius and nominate fuscus, the so called Baltic Gull, all the same species. When I suggested that the remote possibility of a LBBG occuring in Pakistan I was refering to graellsii/intermedius,the westernmost ssp. However Baltic Gull which is smaller and darkest of the three would be the candidate if to turn up in Pakistan. It has an eastern migration route and winters mainly in E. Africa. Status - according to GULLS - status between Arabian Gulf and India uncertain. Heuglin´s Gull is larger and more important paler than Baltic Gull and the gulls in your image is not of Baltic Gull, more certain Heuglin´s Gull as mentioned before. And I think the dark ones is darker because of the angle and therefore affected by the light, but there´s still a contrast between the black primaries and the upperparts. In Baltic Gull you would not see such a contrast since the upperparts are darker,usually concolorous with the primaries. [url]http://www.netfugl.dk/pictures.php?id=showpicture&picture_id=2965[/url] The LBBG that can be very difficult - if not impossible to separate from heuglini is the westernmost graellsii - sharing the similar upperparts tone of grey: [url]http://www.netfugl.dk/pictures.php?id=showpicture&picture_id=3143[/url] But as said Himalaya - range and the fact the numbers on you image - says heuglini before graellsii! Taxonomy in gulls is difficult and there has been several suggestion regarding heuglini, a species of it´s own, or a ssp of LBBG. Now lumped with LBBG. Complicated? Well that gulls for you.
