White-chinned Thrush
Turdus aurantius
A dark plumaged ground feeder that prefers wooded areas but also occurs in gardens and plantations. Its most distinctive features are its bright orange bill and legs. The namesake white chin is inconspicuous. Also note the white slash, which is usually visible, on the upper wing. Superficially similar to the shier White-eyed Thrush, which has a white eye plus a dark bill and legs. Most common call is a slightly shrill, up-slurred “p’weet,” sometimes given as a longer “p’ooo-weeet.” Song is a series of varied sweet notes given singly or as couplets.

The bill, legs and feet are orange. The eye is brown.<p>The only other thrush present in Jamaica is the white-eyed thrush.

分类信息
The white-chinned thrush was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the thrushes in the genus Turdus and coined the binomial name Turdus aurantius. The scientific name comes from Latin Turdus meaning "thrush" and Modern Latin aurantius meaning "orange-coloured". Gmelin based his account on those by earlier authors. His list included John Ray in 1713, Hans Sloane in 1725, Mathurin Jacques Brisson in 1760, Comte de Buffon in 1775 and John Latham in 1783. The species is monotypic: no subspecies are recognised.

行为
Breeding occurs between May and August. The nest is placed in a shrub and is an untidy cup of leaves, fibres and twigs that is lined with finer material. The clutch is 2-4 eggs which are dull whitish or pale green background with reddish brown spots. They are incubated by the female for 16 days. Two broods are usually raised.

Cinnamon Bracken-Warbler
Bradypterus cinnamomeus
Mid-sized warbler with a long tail. Rufous overall, with a white throat and pale eye-line. Found in various open montane habitats, including bracken, heath, dense scrub, and forest edge. Skulks in the understory, though sometimes emerges into the open. The song starts with one or a couple of high notes, followed by a low, loose trill. The call is a peevish “tree-aat.” Similar to Evergreen-forest Warbler, but in most of the range distinguished by much more rufous overall coloration. Around the Albertine Rift, distinguished from the rufous local subspecies of Evergreen-forest Warbler by the well-defined white throat.
Ameline Swiftlet
Aerodramus amelis
Medium-sized brownish swiftlet with a weakly forked tail. Found only in the Philippine lowlands. Typically encountered alone or in loose groups over various open habitats, often soaring high. Fairly uniform brown plumage, lack of a pale rump, and size distinguish this species from most others in the area; Philippine Swiftlet is the most similar but is smaller, has a more square-tipped tail, and generally favors higher elevations (typically 700 meters and above).
Marble-faced Bristle-Tyrant
Pogonotriccus ophthalmicus
Small flycatcher found in foothill and subtropical forest from around 800-2200m. Grizzled face pattern with bold black and white crescent on cheek like some other bristle-tyrants and tyrannulets. Look for all dark bill and yellow wingbars to identify Marble-faced. Sexes alike. Found singly or in pairs, usually in lower to middle levels of forest, often following a mixed speices flock. Voice is also important: a descending sputter followed by a few rising “tseep!” notes.
