Orange-backed Troupial

Icterus croconotus

Big orange-and-black oriole with bare skin around the eye. Bright orange with black tail, wings, and face, light yellow eyes, and a white wing patch. Sexes similar. Distinctive in the Amazon basin, where it is the only large orange-and-black oriole. Found in secondary growth, forest edges, and suburban areas, often near water. Listen for its song, a slow series of whistles.

识别特征

The orange-backed troupial grows to a length of about 23 cm (9 in). In colour it is bright orange apart from a black face, bib, wings and tail, and a small white patch on the secondary wing feathers. It has an orange streak on its shoulder and a small blue ring of bare skin surrounds the eye. The bib has a neat lower edge which helps to distinguish it from the Venezuelan troupial, which has a shaggy base to the bib and a much larger white streak on the wing. The song consists of a number of loud, musical phrases, mostly with two syllables.

St. Lucia Amazon

St. Lucia Amazon

Amazona versicolor

A stout inhabitant of wet montane forests; sometimes ventures into orchards. This species often appears green with a bluish head, though a variable amount of red is present on the chest and belly. In overflight, a small red patch on each wing can be seen above and below. No other parrots occur within its range, and no parrot commonly kept in captivity resembles this species. Calls include a somewhat sharp “ka-chuck” and plaintive “ay-uh.”

Togo Paradise-Whydah

Togo Paradise-Whydah

Vidua togoensis

A nest parasite that lays its eggs in the nests of Yellow-winged Pytilias. As with other whydahs, breeding males are spectacular and bizarre, whereas non-breeding males and females are drab and inconspicuous. Breeding males are mostly black with a rufous breast, a yellow back of the neck, and a long, narrow tail. Non-breeding male and female plumages are poorly known, but show a streaky brownish back and pale underparts. Generally scarce and local in savanna and cultivated areas. Breeding male similar to other paradise-whydahs, but has a longer and narrower tail. Separation of non-breeding male and female from other paradise-whydahs is poorly understood. Not very vocal, but does mimic Yellow-winged Pytilia vocalizations, which include simple, nasal “teew” notes. 

Black-faced Hawk

Black-faced Hawk

Leucopternis melanops

Smallish chunky hawk. Identifiable by size, shape, and prominent black mask contrasting with orange cere. Generally rare. Inhabits wet forests where it hunts from the mid-level to the ground; often perches well below canopy level. Takes relatively small prey, chiefly frogs and snakes. Superficially similar to White Hawk but much smaller with orange (not blue-gray) cere; unlike White Hawk, Black-faced tends not to soar for long periods and is less frequently seen than White Hawk.
