Costa's Hummingbird

(Calypte costae)

The Costa's Hummingbird is a species of hummingbird. Costa's hummingbird is fairly common in the arid brushy deserts and any nearby gardens of the Southwestern United States and the Baja California Peninsula of Mexico.The male Costa's hummingbird's courtship display is a spirited series of swoops and arcing dives, carefully utilizing a proper angle to the sun to show off his violet plumage to impress prospective mates. Each high-speed dive will also pass within inches of the female, perched on a nearby branch, which will be accented by a high-pitched shriek that is produced by the tail. Separately, the male will perch and produce similar sounds in his song—except, the song is vocal rather than tail-generated.
