Thayer's Gull by Ryan ShawThe first galleries are finally published. A collection of first class pictures is picked out from the pool “Gulls of the World” at Flickr. The page will include more pictures when the pool expands. Pictures are presented chronologically based on the individuals age. More species will be available soon, and identification comments will be added continously.

If you want to contribute to the Gallery-pages, share your pictures in the Flickr group “Gulls of the World”. The most illustrative shots will be selected for the galleries, and the rest will be available for the globalgullers through a link on each species gallery.

The kumlieni puzzle

Posted on by

Identification of birds plumaged between Thayer’s and Iceland Gulls has always created debate. Some treat the kumlieni-gulls as a subspecies of Iceland gull, and some mean it is a hybrid between Thayer’s and Iceland Gulls.

North-American based Steve Hampton just published a webpage with a suggested key that can be used to get an indication on what to label individual Thayer’s, kumlien’s and Iceland Gulls in their first winter plumage. The key is based on rating different parts of the birds plumage and bare parts, ending up with a total score which is used for identification. This is the first update, and the author wants comments and feedback to further refine the scales.

Gulls of the World, a group on Flickr.

Created a blog today, hoping the application can support the needs when creating a resource for identification of all the gull-species in the world. All Gull-species of the world will be featured, and illustrations for the species fact-sheets will be picked  from the high-quality pictures from the Gulls of the World-pool at Flickr. The full site was ment to be launched at the Gullfest in Finnmark, Norway in April 2012, but due to unfortunate circumstances it is a bit delayed.
