Did you know there is a species of hummingbird called Anna’s hummingbird? Me neither. But did you also know that the males have this swoopy-diving-lady-attracting dance where they chirp at the bottom of the swoop and that chirp is actually generated by their TAIL FEATHER flapping around in the 50 mph airstream? Yeah. Me neither.
Thanks Berkeley news office!
Man, it must have taken forever to train all those little birds to fly in a line like that.
