FYI: In addtion to the Advanced Birding book that Kim Eckert mentioned, I purchased a book last summer, Peterson's Gulls of the Americas (Jon Dunn, author of the National Geographic Field Guides is a co-author).
It is chock full of photos featuring almost every possible year/cycle/ molt and in the back has lots of information on ID and comparison (including comparing Franklin's and Laughing) Amazon link: http://tinyurl.com/3px5d6 -Derek Bakken Minneapolis, MN www.flickr.com/photos/dobak ornitholature.blogspot.com -------------- next part -------------- An HTML attachment was scrubbed...
