But the original bird looks like an "Iceland" type albeit with a slightly odd head shape and all plumage characteristics are 100% Iceland. The bird you linked while looking very like a Glaucous apart from the bill does have marked primaries. Yes the last gull does have an odd looking head shape and i will post photos tommorrow hopefully showing it in a different more icleand like pose. The bird does look like some Kumliens but again i will post wing shots showing the bird is a "coarse" Iceland GullI believe that the biggest majority of Iceland gulls we recieve in Ireland are most likely females although this is hard to prove, but most are petite things. When you see the odd male you have to work a bit harder to rule out Glaucous. Why we mailny get females i have no idea or theory?As far as i am aware Iceland x Herring has never been proven but must occur even its on very rare occasions. If it is ever proved then birds like Tittletattlers might come into play! all the bestderek</blockquote>
