Anna’s Hummingbird is a common resident from southern California inland to southern Arizona and north to southwestern British Columbia. Their heart rate can reach as high as 1,260 beats per minute,
These birds feed on nectar from flowers using a long extendable tongue. They also consume small insects caught in flight.
Unlike most hummingbirds, the male Anna’s Hummingbird sings during courtship. The song is thin and squeaky. During the breeding season, males can be observed performing a remarkable display, called a display dive, on their territories. When a female flies onto a male’s territory, he rises up approximately 30 metres (98 ft) before diving over the recipient. As he approaches the bottom of the dive the males reach an average speed of 27 m/s, which is 385 body lengths per second. At the bottom of the dive the male travels 23 metres per second (51 mph), and produces a loud sound described by some as an “explosive squeak” with their outer tail-feathers.
