Hummingbird Banding

Southeastern Arizona Bird Observatory conducts hummingbird banding at the San Pedro House during the spring and fall migrations, in April and May, and July through September. Up to 10 species of hummingbirds use the San 

Pedro River corridor as a freeway between their tropical winter retreats and their northern nesting grounds.

Scientists and volunteers capture, weigh, measure, band, and release these tiny travelers as part of a long-term study of bird life and this vital migration route.

Hummingbirds are trapped in a fine nylon mesh before handlers gently complete data collection. The final step of the process is to offer the birds a sip of sugar water, then placed in a waiting hand for release. Often, the birds, weighing less than a paperclip, sit quietly in the palm of your hand before taking flight.
