Anna’s Hummingbirds are among the most common hummingbirds along the Pacific Coast, yet they're anything but common in appearance. With their iridescent emerald feathers and sparkling rose-pink throats, they are more like flying jewelry than birds. Though no larger than a ping-pong ball and no heavier than a nickel, Anna’s Hummingbirds make a strong impression. In their thrilling courtship displays, males climb up to 130 feet into the air and then swoop to the ground with a curious burst of noise that they produce through their tail feathers.
