Up to 10 species of hummingbirds use the green corridor of the San Pedro River as a freeway between their tropical winter retreats and their northern nesting grounds. The public is invited to get a close-up look at these tiny travelers as staff and volunteers from the Southeastern Arizona Bird Observatory capture, band, weigh, measure, and release them as part of long-term studies of the bird life of this vital migration route.
The public is welcome to observe banding sessions at no charge, but donations are gratefully accepted. For more information visit www.sabo.org or call (520) 432-1388.
