The Anna's Hummingbird (Calypte anna) is a medium-sized hummingbird native to the west coast of North America. This bird was named after Anna Massena, Duchess of Rivoli.
Anna's Hummingbird is 9-10 cm (3.5"-4") long. It has a bronze-green back, a pale grey chest and belly, and green flanks. Its bill is long, straight and slender. The adult male has an iridescent crimson-red crown and throat, and a dark, slightly forked tail. Anna's is the only North American hummingbird species with a red crown. Females and juveniles have a green crown, a grey throat with some red marking, a grey chest and belly, and a dark, rounded tail with white tips on the outer feathers.
These birds feed on nectar from flowers using a long extendable tongue. They also consume small spiders and insects which they catch in flight. While collecting nectar, they also assist in plant pollination. They sometimes eat tree sap.
