The white-throated hummingbird is 10 to 11.5 cm (3.9 to 4.5 in) long. Males weigh 5 to 8 g (0.18 to 0.28 oz) and females about 4.5 g (0.16 oz). Adults have a medium length, straight, bill with a blackish maxilla and red mandible with a black tip. Adult males have golden- to bronze-green upperparts. Their uppertail coverts and inner tail feathers are golden-green to brilliant green and the outer tail feathers blackish green with white bands near the end. Their chin feathers are brilliant green with white edges, their throat white, and their cheeks and breast brilliant green to golden-green. The center of their belly is white with golden- to bronze-green sides and flanks. Their undertail coverts are white with some bronze-green to brownish inclusions. Adult females are very similar but duller, less glittery, overall. Juveniles have grayish brown underparts with less white and brownish tips to the tail feathers.
分类信息
French ornithologist Louis Pierre Vieillot described the white-throated hummingbird in 1818 as Trochilus albicollis. Its species name is derived from the Latin words albus "white" and collum "neck". Ludwig Reichenbach erected the genus Leucochloris in 1854, deriving the name from the Ancient Greek leukos "white" and chloros "green".<p>The white-throated hummingbird is the only member of its genus and has no subspecies.

It inhabits semi-open to open landscapes such as the edges of mature forest, marshes, scrublands, parks, and gardens. In elevation it is generally found from near sea level to 1,000 m (3,300 ft) but there are occasional records higher with one at 2,100 m (6,900 ft).

Black-breasted Buttonquail
Turnix melanogaster
Dark buttonquail of forested areas with dense layers of leaf litter in southeastern Queensland. Heavily patterned, with pale and dark mark markings below. Female has a mostly black head, heavily marked underparts, and a pale eye (Painted Buttonquail has a red eye); male has paler face, pale eye, and is less richly marked below. When feeding, this species creates deep, circular depressions in the leaf litter; searching for the presence of these depressions is often the best way to locate it. Vocalizations include a repeated clucking call.
Pink-legged Graveteiro
Acrobatornis fonsecai
Predominantly gray species with a long tail and pink legs. Note the darker gray crown and paler eyebrow. Found principally in shaded cacao plantations or adjacent remnant forests across a very restricted range. Forages acrobatically in the canopy and subcanopy and often accompanies mixed-species flocks. Builds a large stick nest.
Uganda Woodland-Warbler
Phylloscopus budongoensis
A small, active warbler of lowland and mid-elevation forest understory that is green above and gray below with a noticeable pale eyebrow. Similar to migratory warblers, especially Willow Warbler, but note Uganda Woodland-Warbler’s grayer underparts, paler throat, and yellowish vent. Song is a fast, jumbled mix of high-pitched notes.
