High-speed courtship dive of the Anna's Hummingbird

Male Anna's Hummingbirds perform a spectacular courtship dive to females, at the bottom of which they abruptly produce a loud "CHIRP" sound with their tail-feathers. The image was created from a high-speed video; each image is 0.01 seconds apart.
