Jamaican Lizard-Cuckoo
Coccyzus vetula
An impressive long-tailed bird of moist mid-elevation woodlands including secondary growth, where it feeds in the understory by peeking and probing into vegetation in pursuit of insects and lizards. Generally solitary and secretive, but not shy. Note this species’ long, straight, narrow bill and buff underparts. The Chestnut-bellied Cuckoo is similar in overall shape, but it is somewhat larger with a chestnut belly and a grayish chest; also note its bill is much shorter and somewhat curved compared to Jamaican Lizard-Cuckoo. The passingly similar Mangrove Cuckoo is somewhat smaller, shorter billed, lacks an eyering, and has a black mask. Jamaican Lizard-Cuckoos are often first detected by voice: a rapid-fire, ratcheting “k-k-k-kuh-kuh-kuh-kuh-kuh…” that grows slower and louder as it progresses; usually given at a uniform pitch.
识别特征
The Jamaican lizard cuckoo is 38 to 40 cm (15 to 16 in) long, about half of which is the tail, and weighs 86 to 105 g (3.0 to 3.7 oz). It has a long, straight, rectangular bill with a black maxilla and a paler mandible. The sexes have the same plumage. Adults have a brown forehead, crown to below the eye, and nape. Their upperparts are grayish with rufous primaries. Their throat is whitish and the rest of the underparts are rufous that is lighter on the undertail coverts. Their tail feathers are gray with wide white tips; the central pair have a black band above the tip. Their eye is surrounded by bare red skin. Juveniles have narrower tail feathers than adults and buffy tips on the secondaries.
分类信息
The Jamaican lizard cuckoo and three other lizard cuckoos were for a time considered a single species. Individually they were previously placed in genus Saurothera that was later merged into the current Coccyzus, and they are considered a superspecies. The Jamaican lizard cuckoo is monotypic.

行为
The Jamaican lizard cuckoo is not migratory.<p>The Jamaican lizard cuckoo forages mostly from the forest mid-story to the canopy, running along branches and gliding from tree to tree. Its diet is cosmopolitan and includes Anolis lizards, adult and larval insects, mice, nestling birds, and sometimes tree frogs. Young are fed mainly with lizards.<p>The Jamaican lizard cuckoo's breeding season generally spans from March to August, though courtship has been observed in October. It makes a flat platform nest of twigs lined with leaves, placed well hidden in a tangle of branches or bromeliads. Both adults incubate the eggs and care for nestlings.<p>The Jamaican lizard cuckoo's principal vocalization is a "[r]apid, low 'cak-cak-cak-ka-ka-ka-k-k'."

Slender Sheartail
Doricha enicura
Small hummingbird of scrubby forests and overgrown clearings in the mountains of Chiapas and south to southern Honduras. Feeds quietly at all levels and is easily overlooked. Note the long arched bill; distinct from other small hummingbirds in its range. Spectacular male has very long blackish tail (forked, but usually held closed in a point) and green-and-purple throat (usually looks dark). Female is buffy below.
Brown-cheeked Hornbill
Bycanistes cylindricus
Big, spectacular black-and-white hornbill. Males have a large cream-colored bill, and females a much smaller and darker one. In flight, shows a broad white patch at the back of the wing, white wingtips, and a white tail with a black band. Found in the canopy of lowland rainforest, usually in pairs or small groups. The loud calls are honking and yapping notes that are often given in a quick series. Similar to Black-and-white-casqued Hornbill, but has a white tail with a black band, the wingtips are white, and the bill is paler. Could be confused with Piping Hornbill, but much larger, with much more white in the wings and tail and a paler bill.
