1st of April, but no fooling!

It is so nice that the gulls are back in numbers again, even though the numbers are small still. Today I had 13 Glaucous Gulls (Polarmåke) feeding on bread in front of me, in addition to a subadult Iceland Gull (Grønlandsmåke) and a strange-looking Herring Gull (Gråmåke). I am not sure of the true nature of the species of this "Herring Gull". It felt like a HG when it was flying, but the markings both above and below the wings were very small. The markings on top of the wings consisted of very little black, with large white mirrors, and some long black tongues where I expected to see pure black. The markings on the underwing were very faint, almost pale brown and not covering a large part of the normal area. This led mythoughts into a possible hybrid glaucous x herring. I have seen a few such hybrids before, but none of them have shown a pattern similar to this. While trying to figure out the nature of this bird I came across a few pictures that fitted pretty well, but I still have my doubts about it. These pictures were of Thayer's Gull (Eskimomåke). I feel that this gull may be too large for a Thayers, but I am not the one to come with proper suggestions on this gull. If there is one thing I have learned about gulls, and Herring Gulls in particular, it has to be that gulls vary so much that you can seldom be too certain if youre not an expert. And I am clearly not one! I have allready asked a couple of people about comments regarding this gull, but feel free to comment if you have a good idea of what it is that I have seen.

  1. Det var mange gode fluktbilder, ikke lett å få dem i fokus med vann i bakgrunn.

  2. når de kommer så nærme så hjelper de jo til litt ufrivillig :)
