Click on the species names in the menu to the left to access an index of pages and images for each species. 


To facilitate discussion about individual gulls, each individual image is identified with a unique code.  The code takes the form of 4 letter band-type code (unique to the species concerned) followed by an underscore and then a number (unique to the individual image) - e.g. GLGU_04 for image 4 of a Glaucous Gull.  The codes appear at the end of the caption for each image and also on the index page for each species.  For presumed hybrids, the letter part has been expanded to indicate which species are thought to be involved (e.g. GWxAHGU_03 for image 3 of a presumed Glaucous-winged x American Herring Gull hybrid). Many thanks to Richard Millington for his suggestions.  All comments regarding identification, layout etc. are most welcome (e-mail me).
