The obvious Nelso...I like where you are going here. The obvious Nelson's 1C phenotype is a big GLGU shaped bird with some brown coloration on the flight feathers. But when you start to take on the consideration that shape can also vary between the two parent species it opens the floor up to many possibilities, such as the birds you have here. I thought the shapes, with the exception of the GLGU-like first bird looked much more HERG. I don't see any sign of typical GLGU 1C patterning on the mantles of these birds but is that a strike against being a hyrid? I don't see why it should be but willing to learn why if so. The older birds with paler gray mantles further give evidence to your point I think. Apparently Nelson's breeding sites are largely scattered, few and unknown in the Canadian arctic. Surely there is something to be learned from Viking Gull that would help locate more? Anonymoushttps://www.blogger.com/profile/17032255318454062102noreply@blogger.com
