Anna’s hummingbird (Calypte anna) is known for its striking iridescent pink throat and crown. The males have a classic mating ritual where they perform a “shuttle” behavior where they fly from side to side, and then sing a high-intensity song. This is done in the female’s nesting area and occurs directly before mating.
