The Anna’s Hummingbird is a medium-sized hummingbird of the western United States measuring about 3 ½ inches in length. The male has an iridescent red crown, face, and gorget (throat). The back, wings, and tail are glossy green, and the underparts are white. It is the only American hummingbird with a red crown. Females are similar but have a green crown and face and a grayish throat (some have a hint of red). Males engage in elaborate defense displays in which they rise to heights of 100 feet or more before diving straight down at the target. About a foot from the target, the bird pulls up and delivers a shrill squeak.
