Anna's hummingbird at her nest. Feeding her two babies, only few days old. California.
Anna's Hummingbird (Calypte anna) is a medium-sized hummingbird native to the west coast of North America. This bird was named after Anna Masséna, Duchess of Rivoli. The female raises the young without the assistance of the male. The female bird builds a large nest in a shrub or tree, or in vines or on wires. The round, 3.8-to-5.1-centimetre (1.5 to 2.0 in) diameter nest is built of very small twigs, lichen and other mosses, and often lined with downy feathers or animal hair. The nest materials are bound together with spider silk or other sticky materials. They are known to nest early as mid-December and as late as June.
