Anna's Hummingbird
Calypte anna
Hummingbird
Length: 4 in. (10 cm )
The most common urban hummingbird in the far west, the Anna\'s Hummingbird has considerably expanded its range north and east in the last 25 years, mainly because of the availability of exotic flowers, eucalyptus trees and year round hummingbird feeders. The male is often first noticed by its squeaky song. It breeds 2 or 3 times a year and begins its first nest in December in the desert southwest. The tiny nest is held together by spider webbing and is usually at eye level in a thick bush or vine.
The four-digit banding code is ANHU.
