Costa's Hummingbird

Found from western Arizona and adjacent Nevada and California south through coastal northwestern Mexico, the Costa's is a desert hummingbird. Birds in Arizona migrate south after breeding in the spring. Although these hummingbirds fly-catch, they are common only when nectar sources are abundant (mainly chuparosa or ocotillo). Vagrants occur north to Alaska and east to Kansas (Baltosser and Scott 1996). One advantage to a zoo like the Arizona Desert Museum in Tucson is that the birds can not fly far.
