Anna's Hummingbird (immature male) in flight. Hummingbirds have an incredible metabolism with a heartrate of 1260 beats per minute! The rate of wingbeat is 45 beats per second, giving the birds their humming sound as they fly. Their diet consists of high calorie flower nectar (or sugar water from feeders) and small insects. The body length of these tiny birds is only 4" and they weigh in a less than an ounce!
