When: Throughout August. Where: San Pedro Riparian National Conservation Area, AZ. What: Beginning with spring migration, hummingbirds fly along the San Pedro River en route to their nesting grounds. Up to 14 species stop off at the feeders of the San Pedro House, where staff of the Southeastern Arizona Bird Observatory capture and put ID bands on their legs for research before setting them back on their migratory path. A great opportunity to get close-ups of the iridescent, jewel-like birds. Tip: After banding, volunteers give the hummer a sip of nectar and often place one in a visitor’s hand, giving you a chance for tight shots. Bring a friend to “lend a hand.” For Info: www.sabo.org; 520-432-1388.
