Joe, A lot of your questions would be answered for you by materials available from the American Birding Association. If you're not yet a member, I highly recommend it--they have an extensive catalog of useful publications (more than you might think for Southeastern Arizona), checklists, member networks in all segments of the country, etc. The ABA Guide to Southeastern Arizona will answer most, if not all, of your questions. You can reach ABA Sales at 1-800-634-7736. Norm =============== Norm Saunders Colesville, MD osprey@ari.net
