Hello, Thought I'd let you know that for three years now, Dave Silverman, of Rye, CO, has compiled what he calls "The PUEBLO CO AREA MIGRATION CALENDAR"...which includes information from several many folks in Pueblo and surrounding Counties. While not Colorado in total, and understanding maybe three years doesn't 'historical' make...it could be useful to you. Dave ([email protected]) is a long-time birder with exquisite talents and one of the nicest people around. He's made copies of his work available to those who ask. It's quite detailed (18 pages) and more than a little interesting...
