Purple-throated Carib
Eulampis jugularis
A large hummingbird with a markedly downcurved bill. It appears largely black in most lighting conditions, though its shimmering green wings are usually still visible. Those green wings along with a more strongly curved bill, help separate this species from the Green-throated Carib. Mostly found in forests, occasionally at forest edges, and infrequently elsewhere. Calls include a sharp high tsweet and a variety of twitters.
识别特征
The purple-throated carib is 11 to 12 cm (4.3 to 4.7 in) long. Males weigh 9 to 12 g (0.32 to 0.42 oz) and females 7 to 10 g (0.25 to 0.35 oz); specimens of unrecorded sex weighed 6.7 to 10.8 g (0.24 to 0.38 oz). The adult male and female have the same plumage. Their crown and back are velvety black, the throat and chest fiery purplish red, the wings bright golden green, and the tail and its upper and lower coverts metallic greenish blue. The male has a medium length slightly decurved bill; the female's is longer and more strongly curved. Immatures have an orange throat and chest with red speckles.
分类信息
The purple-throated carib was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his Systema Naturae under the binomial name Trochilus jugularis. Linnaeus based his short description on the "red breasted humming bird" that had been described and illustrated by the English naturalist George Edwards and the "colibry violet de Cayenne" that had been described and illustrated by the French zoologist Mathurin Jacques Brisson. Edwards believed his specimen had come from Suriname, Brisson believed his specimen had come from Cayenne, but both authors were mistaken, as the purple-throated carib is only found on the islands of the Lesser Antilles. The specific epithet jugularis is Medieval Latin for "of the throat". The purple-throated carib is the type species of the genus Eulampis that was introduced in 1831 by the German zoologist Friedrich Boie and which it shares with the green-throated carib (E. holosericeus). The species is monotypic: No subspecies are recognized.

分布与栖息地
The purple-throated carib is resident on Antigua, Dominica, Guadeloupe, Martinique, Montserrat, Saba, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and Sint Eustatius. It has occurred as a vagrant in Barbados, Barbuda, Grenada and the Greater Antilles. It inhabits the interior and edges of primary and secondary forest, mostly at elevations between 800 and 1,200 m (2,600 and 3,900 ft).

Greater White-fronted Goose
Anser albifrons
Medium-sized goose with extensive range across the Northern Hemisphere. On adults note bright orange legs, white face, and variable amount of black splotching on belly. Bill color varies from orange to pinkish. Immatures lack white face and black on belly and have duller orange legs and bill. Superficially similar to domestic barnyard geese but smaller without the enormous pot-bellied appearance of domestic birds. Bill color is helpful to separate from both species of Bean-Goose and Pink-footed Goose. Also compare with very similar Lesser White-fronted Goose in Europe and Asia, which is smaller and more compact, and has a stubby bill and yellow eyering. Breeds in tundra and taiga habitats; winters in fields, agricultural areas, and wetlands. Usually found in flocks, sometimes mixed with other species of geese.
Denham's Bustard
Neotis denhami
A large-to-medium-sized bustard with a chestnut nape and hind neck, and pale gray fore neck. The grayish head has distinct black-and-white crown stripes. Female and juvenile are smaller than male. Pairs and small groups march purposefully in grassland, wooded savanna, and fallow cereal fields, foraging on plants and small animals. It is a partial migrant, moving with the rains. The much larger Kori Bustard has a barred, grayish neck; Ludwig’s Bustard has a gray-brown fore neck, rather than pale gray fore neck of Denham’s Bustard.
Chestnut-colored Woodpecker
Celeus castaneus
Attractive, medium-sized crested woodpecker of humid tropical lowlands. Uncommon in evergreen forest and edge ranging into adjacent clearings with taller trees. Forages mainly at middle to upper levels, where often quite inconspicuous. Both sexes bright chestnut-brown overall with blond, shaggy, slightly wobbly crest. Male has big red mustache.
