Also known as the Cuban or Black-billed, the West Indian Whistling Duck is widely scattered throughout the West Indies.  It is largely sedentary, apart from local movements, which can be 100 km or more.  

By nature they are nocturnal and pretty secretive in the wild. 

They are the largest of the whistling ducks, with a long black bill, long head and longish legs. They have a pale fore-neck and light brown face. The crown, back, breast and wings are dark brown to black, and the rest of the underparts are white with heavy black markings. The overall appearance makes them the darkest of the genera.

For many years, the whistling ducks were known as tree ducks. The West Indian Whistling is one of the species worthy of the original name; it does indeed habitually perch in trees.
