Anna's Hummingbird

Anna's Hummingbird (Calypte anna) is a medium-sized bird species of the family Trochilidae. It was named after Anna Masséna, Duchess of Rivoli. It is indigenous to western North American coastal regions. Only southern California and northern Baja California hosted breeding populations of Anna's hummingbirds in the early 20th century. The species was able to increase its breeding range thanks to the transplantation of exotic decorative plants into residential areas along the Pacific coast and in inland deserts, which offered more nectar and nesting locations.

The wingspan of Anna's hummingbirds is 4.7 inches (12 cm), they range in size from 3.9 to 4.3 in (9.9 to 10.9 cm), and they weigh between 0.1 and 0.2 oz (2.8 to 5.7 g). Their flanks are green, and their back is an iridescent bronze-green with a pale grey belly and chest. They have long, erect, and slender bills. The adult male has a dark, somewhat forked tail and an iridescent crimson-red to reddish-pink crown and gorget, which can seem dull brown or gray in the absence of direct sunlight. Although they are often smaller and less spectacular than those of the males, females also feature iridescent red gorgets.
