Anna’s hummingbird (Calypte anna), a medium-sized hummingbird native to the west coast of North America, was named after Anna Masséna, Duchess of Rivoli. In the early 20th century, Anna’s hummingbirds bred only in northern Baja California and southern California. The transplanting of exotic ornamental plants in residential areas throughout the Pacific coast and inland deserts provided expanded nectar and nesting sites, allowing the species to expand its breeding range.
