During observations to the northern part of Norway from February 28th – 3rd of march 2013 I shot images of a very pale gull, what I thought at that time was a regular adult Iceland gull. But I showed the image – more by accident – in the BirdForum and one of the experts asked for more pics of that bird to verify if the seemingly dark grey outer webs of P9-10 are real or just a light effect. I send the images and now they think it is a Kumlien’s Gull (Larus glaucoides kumlieni).
Kumlien’s Gull is a large gull which breeds in the Arctic regions far west of Varanger. The main breeding sites are in Canada. But Kumlien’s Gull is migratory, wintering from Labrador west across the Great Lakes and south to New England There are some observations outside that range. Thus the bird is quite a regular vagrant in small numbers to Scandinavia, Great Britain, Ireland and the Atlantic islands. So there was one observation in January 2012 near Trondheim, Norway or in February 2009 on Madeira. According to http://madeira.seawatching.net/articles/Kumliens_2009_Madeira.pdf there has been an unprecedented influx of Kumliens Gulls into Southern Europe in the early part of 2009. Numbers involved are difficult to gauge but as many as ten could have been recorded in Spain where previously only two birds had been recorded before. Others were recorded in Belgium and Portugal, with a single adult also seen on the Azores.
The reason for this influx is Continue reading Kumlien’s Gull (Larus glaucoides kumlieni) on Varanger, Norway
