I'm trying to get better at gulls. I've done some light studying of
the *Peterson
Reference Guides to Gulls of the Americas *(
http://www.amazon.com/Peterson-Reference-Guides-Gulls-Americas/dp/0618726411/).
The information is interesting and in-depth, but it still is difficult for
a beginner to apply (or at least for me to apply). I went out yesterday
feeling informed and prepared and immediately found an adult gull that I
couldn't ID, even with decent (if distant) looks and the book in hand.

Pages like the TheBirdGuide.com (http://thebirdguide.com/gulls/) complicate
matters even more, noting that western gulls in the pacific northwest are
lighter than most field guides acknowledge.

Does anyone have recommendations for how to get better at gulls? Are there
books I'm missing? Are there courses available in the Seattle area? What I
would really love is a decision tree for northwest gulls, even if only for
adults.

Thank you!
