Jamaican Mango
Anthracothorax mango
A large dark hummingbird of forest edges, plantations, and gardens. Its black underparts, iridescent red cheeks, and red-purple tail are unique within its range. Note that females and immatures of this species are not as vivid as males. Call is a sharp “tsic,” given individually or in a series.
识别特征
The Jamaican mango is 11 to 12 cm (4.3 to 4.7 in) long and weighs 8.5 to 9.1 g (0.30 to 0.32 oz). It differs from all others of its genus by being dark overall rather than mostly bright green. The adult male's crown is dull green, the sides of the head and neck metallic magenta, and the back dull greenish bronze. The central tail feathers are dusky bronze to dull black and the rest metallic violet with a thin dark blue band. The underparts are velvety black. The adult female is similar but with faded velvety green flanks and white tips on the outer tail feathers. The immature male has a deep blue throat that becomes the adult's black after its second year.
分类信息
The Jamaican mango was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Trochilus mango. Linnaeus based his description on the "Mango bird" that had been described and illustrated in 1738 by the English naturalist Eleazar Albin. The Jamaican mango is now placed in the genus Anthracothorax that was introduced in 1831 by Friedrich Boie. The species is monotypic: No subspecies are recognized.<p>There is some evidence that the species is the most basal within the genus Anthracothorax.

分布与栖息地
The Jamaican mango is found throughout the eponymous island, with the densest population being along the northern coast. It inhabits a wide variety of open and semi-open landscapes including forest edges, gardens, plantations, and arid areas. It shuns mangrove areas. In elevation it mostly ranges from sea level to 800 m (2,600 ft) and is regular but rare as high as 1,500 m (4,900 ft).

行为
The Jamaican mango moves from the higher elevations to mid levels in June to August after the upper flowering season ends.<p>The Jamaican mango feeds on both nectar and arthropods. It takes nectar from a large variety of flowering trees, shrubs, and vines, both native and introduced. Males defend flowering trees. Insects are mostly taken on the wing.<p>The Jamaican mango nests at any time of the year, though most frequently between January and May. It weaves a small cup nest of soft plant fibers and seed down with spider silk on a thick tree branch, typically between 3 and 8 m (9.8 and 26 ft) above the ground. The clutch size is two eggs. The incubation period and time to fledging are not known.<p>The Jamaican mango is not highly vocal and its song has not been described. Its call is "a sharp, raspy 'tic...tic...tic'."

Black-faced Grassquit
Melanospiza bicolor
Small sparrowlike bird found in the Caribbean and northern South America. Males are dull olive above with a variable amount of black on the face and breast. Females are plain grayish-olive overall; note the small size, short tail, and pinkish bill and legs. Very similar to female Sooty Grassquit. Found in pairs or small groups in shrubby or grassy areas and forest edge, typically on or near the ground.
Greater Yellow-Finch
Sicalis auriventris
Fairly common in the Andes of central Chile and adjacent Argentina; seen readily at ski resorts, around villages, on bogs, and on stony and grassy slopes. Often in flocks, associates readily with other seed-eating birds. Feeds mainly on the ground, but sings from prominent perches such as a rock or building. Not appreciably larger than other yellow-finches, but no similar species in most of range. May overlap in winter locally with Greenish Yellow-Finch, which has shorter wings and a shorter bill, and male never is as bright golden as the Greater Yellow-Finch.
Eastern Bristlebird
Dasyornis brachypterus
Small, long-tailed terrestrial bird of southeastern New South Wales and ranges on the Queensland border. Mottled grayish brown, paler below, with red eye, reddish wing, pale throat, faint pale supercilium, and long, graduated rusty tail. Dark bristles around bill give this species its name. Runs around on the ground in forested areas with dense understory, as well as in coastal heathland, and rarely seen in flight. Calls include a chirpy whistled "chip chip whirr-eee."
