The anis (Crotophagidae) are a small family of gregarious birds occurring in the Americas. They are part of the cuckoo order Cuculiformes and are sometimes placed as a subfamily Crotophaginae within the cuckoo family Cuculidae.
Among the anis, there is considerable variation in nesting habits. One species, The Greater Ani C. major lays 2 or 3 eggs, while the Groove-billed Ani C. sulcirostris lays seven. However the Smooth-billed Ani C. ani will share one nest between several females, with up to 29 eggs in one nest. Incubation takes 15 days for this species.
