Habits: A nocturnal bird, hiding in dense foliage, thickets or caves during the day. Calls in the early morning and evening.
Voice: The male's main call is a short guttural quavering trill of 3-5 seconds duration. He also has another shorter trill which begins softly and rises in pitch and volume to a maximum and quickly fades away. The female's call is similar, but higher in pitch. The contact call is believed to be a soft, cackling gu-gu. They also make a loud coo-coo call, which is how it gets the name of "Cuckoo Bird" in the Virgin Islands.

Breeding: Breeding season is believed to be April to June. They generally nest in tree hollows and cliff crevices. The female lays 2-3 white eggs, and is fed by her mate as she incubates them.

Distribution: Puerto Rico, Isla de Vieques, Isla de Culebra, and adjacent Virgin Islands.
