Joel,

I have a bird book for my local area called "Birds of Illinois Field Guide" by Stan Tekiela. It is a great resource for me to identify birds. Mr. Tekiela is also a nature photographer and does a great job, but even a lot of his pictures fall a fair deal short of yours. I don't know how lucrative the bird book business is, but your images would certainly appear to quality.

This is the link for his book: http://www.amazon.com/Birds-Illinois.../dp/1885061749
