The Anna's Hummingbird, Calypte anna, is a permanent resident in much of its range, which includes
most of the warmer coastal areas of the west coast of North America up to southwestern British Columbia.
The Anna's Hummingbird is a beautiful "hummer" with its characteristic iridescent colours which seem to come alive in certain light. By changing the angle of its feathers and the light which hit them, the male (above) can turn on its rose-red crown and throat.
Both sexes are green on the back and light on the underside. The female (left) lacks the iridescent colours, except mature ones have a small patch on the throat. The bright rose-red of the male looks black when it is turned "off."
The Anna's Hummingbird is only about 3.5 in/ 9 cm long. It uses its straight black bill to access nectar in flowers. It also feeds on insects and spiders. It is generally a solitary and territorial bird.
