Chestnut-bellied Cuckoo
Coccyzus pluvialis
A large species with an impressive tail and a chestnut belly. Found in wooded habitats between 400 and 1500 meters in elevation, particularly wet, open forests; stalks prey by walking and sometimes running along tree limbs. Flight is often a rapid flapping followed by long glide. The Jamaican Lizard-Cuckoo is similar in overall shape, but it is somewhat smaller, has a longer straighter bill, and a buff (not chestnut) belly. This species is often heard before it is seen. Call is a low, harsh, growling “aahhhh” or “aahhhh-ahh.”
识别特征
The chestnut-bellied cuckoo is 48 to 56 cm (19 to 22 in) long, about half of which is the tail, and weighs 130 to 189 g (4.6 to 6.7 oz). The species' blackish bill is stout and decurved. Males and females have the same plumage. Adults have dull brown upperparts, a light gray face and breast with a paler throat, and a dark rufous belly. Their tail is black with large white tips and a purple gloss. Juveniles have a dark brown tail with white tips but no gloss.
分类信息
The chestnut-bellied cuckoo was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other cuckoos in the genus Cuculus and coined the binomial name Cuculus pluvialis. Gmelin based his account on those of earlier authors include that of the Irish physician, naturalist and collector Hans Sloane. Between 1687 and 1689 Sloane lived in Jamaica. In the account of his stay, which was not published until 1725, he described the chestnut-bellied cuckoo under the names "Old-Man" and "Raine-bird" and explained that "It makes a noise generally before rain, whence it had its name of Rain Bird". The chestnut-bellied cuckoo is now placed with 12 other species in the genus Coccyzus that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot. The genus name is from the Ancient Greek kokkuzō meaning "to cry cuckoo". The specific epithet pluvialis is Latin meaning "relating to rain". <p>The chestnut-bellied cuckoo was at one time placed in genus Piaya which was later merged into genus Hyetornis. That genus was in turn merged into the current Coccyzus. The species is monotypic.

分布与栖息地
The chestnut-bellied cuckoo is found throughout most of Jamaica. It inhabits mature evergreen forest, secondary forest, thickets and brushy areas, and semi-open woodlands. In elevation it ranges from sea level to above 1,500 m (4,900 ft).

Red-legged Honeycreeper
Cyanerpes cyaneus
Small, warbler-like tanager of tropical lowlands. Favors forest edge, woodland, and semi-open areas with taller trees. Often occurs in small groups, sometimes larger flocks, usually in the canopy of flowering trees, where it probes for nectar with its long bill. Red legs are bright on male, dullest on young birds. Male is blue in breeding plumage, with a turquoise cap; female and non-breeding male are greenish overall with faint streaking on the chest. In flight, the underside of the wings flash bright sulphur-yellow.
Violet Woodhoopoe
Phoeniculus damarensis
An elongated black bird with a coppery-purple metallic sheen and a long, decurved red-orange bill. The juvenile has a dark bill, but is often in the company of adults. The species flies heavily with the white-tipped tail dangling. Pairs and groups of 3-12 are highly social, occupying arid savanna, woodland, and riverine forest along the Namib escarpment, where they nest and roost in natural cavities. They clamber in trees, probing bark and crevices for insects and small vertebrates, and communicate using a strong cackling chatter that is almost maniacal. The almost identical Green Woodhoopoe (with which this species sometimes hybridizes) only differs from Violet Woodhoopoe by having a glossy-greenish (not coppery-purple) metallic sheen.
Glaucous-blue Grosbeak
Cyanoloxia glaucocaerulea
A medium-sized bulky finchlike species with a small head and a thick bill. Males are blue overall with a glossy blue forehead and rump. Females are dark-brown above and paler below. Found at the edges of second growth and woodlands, typically singly or in pairs and normally very shy. Considered a partial austral migrant, moving a bit further north from the southern limit of its range in winter.
