Interesting adult gull using roof tops of Pentrebach retail park at the moment, has certain attributes of caspian, as can be seen, but refusing to show wing tip pattern so unable to confirm. If you are passing can you check it out. Bird very distant in poor light then heavily cropped, difficult to approach.
I no expert but it dont look quite right for me and I am not see in the real sloping head .
ReplyDeleteHiya, the head is not the typical pear shape, you are right. What made it stand out from "normal" adult herring gull[c20] present were; black eyes, bill colour, gonys angle and what appear to be thin long legs. I don't know what it is, I was hoping a good view of wing tip would give some pointers. The paper on the identification of this species is made up of 2 parts and consists of 81 sides of A4. The 1st part[41 pages]; typical birds, is the easy bit, the 2nd part[40 pages]; phenotypic variability and the field characteristics of hybrids is a corker. To prove id of this species it appears you have to provide good quality images; which is difficult up this end because we can rarely get close to them that is if we can find them, oh hum. See you.
