Puerto Rican Lizard-Cuckoo

The Puerto Rican lizard cuckoo is 40 to 48 cm (16 to 19 in) long, about half of which is the tail. It has a long decurved bill with a black maxilla and a yellow mandible with a black tip. Both sexes have the same plumage. Adults have entirely gray-brown upperparts. Their throat and breast are gray and the belly and undertail coverts tawny. The upper surface of their tail is gray-brown and the underside gray brown darkening to black near the large white tips. Their eye is surrounded by bare red skin. Juveniles have a cinnamon wash on the breast, less black on the underside of the tail, and an orange-red eye ring.

The Puerto Rican lizard cuckoo is found throughout the main island of Puerto Rico. It might have once resided on Vieques, and a single specimen believed to be a vagrant was once collected on St. Thomas in the American Virgin Islands. It inhabits a variety of forested landscapes including semi-open woodlands, dense montane forest, dry coastal forest, and swamp forest. It is also found in coffee plantations and brushy limestone hills. In elevation it is most common between sea level and 900 m (3,000 ft) but it can also be found almost to the highest peaks of the island.

The Puerto Rican lizard cuckoo mostly forages for prey from the middle to upper layers of the forest, though it also hunts in the understory and on the ground. It hunts by stealth, climbing along tree branches or walking on the ground. Its principal food is lizards (especially Anolis) and also includes adult and larval insects, eggs, and occasionally frogs.
