The courtship of Anna’s hummingbird (Calypte annae) is marked by the extraordinary display of the male soaring and diving in flight. After mating, the female gathers materials to build a nest and during this time the female will make 150 trips per day to gather the materials to build the nest. The nest building process will take a week. The female will lay two eggs and the incubation process will take between 12 – 20 days. Once hatched, the chicks are fed predigested food.
