I think that 2nd-winter Thayer's Gulls is yet (and perhaps never will be?) a precise science and I think that Garner/Gibbins focus on birds in December whereas a couple of months on the birds seem to show overall a lot more wear and I guess this is reflected in the primary fringing being more extensive on my visit. As an example, look at the recent Thayer's Gull in Spain (now an adult of course) when it was around in March 2010 http://www.rarebirdspain.net/arbsr1003.htm#Lartha (scroll down)RBhttps://www.blogger.com/profile/08818526650971120952noreply@blogger.comtag:blogger.com,1999:blog-5864753765745920625.post-62813617617065152282013-03-17T20:43:50.795+00:002013-03-17T20:43:50.795+00:00Hi Rich, Having seen your shots I was wondering ab...Hi Rich, Having seen your shots I was wondering about the extent of pale fringing on the primaries.The Garner/Gibbins article says, i think,the pale fringe should be more or less confined to the tip of the primary but some of your birds show a more extensive fringe especially on some inner primaries. Just wondering if its a more variable feature than previously suggested. Paul Moore, CorkPaul Moorehttps://www.blogger.com/profile/10053566613388915275noreply@blogger.com
