Hispaniolan Lizard-Cuckoo

Identificazione

The Hispaniolan lizard cuckoo is 41 to 46 cm (16 to 18 in) long, about half of which is the tail. Males weigh about 83 to 99 g (2.9 to 3.5 oz) and females about 92 to 128 g (3.2 to 4.5 oz). Both subspecies have a long straight bill with a black maxilla and a paler mandible. The sexes within a subspecies have the same plumage. Adults of the nominate subspecies have entirely gray upperparts. Their wings are chestnut with a rufous patch. Their throat is rufous, the breast pale gray, and the belly rufous. Their tail is black, and the underside of the feathers have large white tips. Their eye is surrounded by bare red skin. Juveniles have brownish gray upperparts, a whitish throat, and a narrower brown tail with buff tips. The subspecies C. l. petersi is paler overall than the nominate, and has a whitish throat.

Tassonomia

The Hispaniolan lizard cuckoo and three other lizard cuckoos were once considered a single species. Individually, they were previously placed in the genus Saurothera that was later merged into the current Coccyzus, and they are considered a superspecies. All four of them are endemic to islands in the Caribbean. The Hispaniolan species has two subspecies: the nominate C. l. longirostris and C. l. petersi.
