Cuban Nightjar (Antrostomus cubanensis) used to be known as Cuban Antillean Nightjar but several authorities now consider the bird that occurs in Cuba to be a separate species to the one on Hispaniola. It is a widespread resident though like all nightjars they are not often seen. I haven't knowingly heard it before though that's probably because we've never been to Cuba in the spring and rarely in the summer months. The call is very distinctive though and you can listen to it here. These wonderful photos were taken by bird guide Karlos Ross in Holguin province in the east. Thank you Karlos.

The Smooth-billed Ani is a gregarious species that is common in Cuba, Hispaniola, parts of Central America and much of South America. It also occurs in Florida but is declining there due to a loss of habitat and lack of protection.
They live in family groups of up to about thirty birds and build a communal nest in which the females of the group all lay eggs though the earlier ones that are laid often get buried and covered with a layer of leaves so only the later ones that are laid get to hatch. The young are then reared by all members of the group including earlier broods.
The wonderful photo above was taken by Roberto Jovel near Baracoa in the east of Cuba.
