Greater Flowerpiercer

Diglossa major

Small, dark gray bird of highland forest. Gray plumage is set off by chestnut undertail coverts and black mask and chin, which contrast with the pale silvery bill. Distinctive bill shape can be difficult to discern at a distance. Found only at high elevations (above 1000 m) in the tepui highlands, where it is a locally fairly common resident of humid forest and scrub. In taller forest, it is generally in the canopy but may occasionally descend into the understory. Often observed at fruiting and flowering trees and shrubs, where it plucks fruit and pierces into the bases of flowers to drink nectar. Also follows mixed-species flocks. Unusual song is a mix of high peeping and harsh grating notes; the peeping notes are also given as a contact call. Considerably larger than other flowerpiercers, and unlikely to be mistaken for other species in its limited range.

识别特征

The greater flowerpiercer grows to a length of about 16.5 cm (6.5 in) and is larger than any other species in the genus. The adult has a black mask but is otherwise a bluish-slate colour, with a silvery moustachial streak and silvery streaks on the crown and mantle. It has a chestnut crissum (the area around the cloaca). It is unlikely to be confused with related species because no other members of the genus shares its range.

分布与栖息地

The greater flowerpiercer occurs around the tepuis (flat-topped mountains) that are found in the southeastern part of Venezuela and the adjoining areas of northern Brazil, eastern Bolivia and western Guyana. Its altitudinal range is from 1,300 to 2,800 m (4,300 to 9,200 ft) but it is most common above 1,800 m (5,900 ft). It typically occurs in clearings and edges of montane forest, in shrubland and stunted woodland.

Tringa erythropus

Elegant wader with a long fine bill and long reddish legs (dark on breeding adults). Striking breeding plumage dark overall. Nonbreeding plumage is paler and grayer than smaller and chunkier Common Redshank. In flight often appears dark overall with narrow white oval up middle of back. Breeds in arctic bogs and swamps; migrants occur in varied wetland habitats. Usually seen as singles or small groups, though will sometimes congregate in large flocks, especially on wintering grounds. Feeds mainly by wading in fairly deep water, probing and picking with its bill, at times swimming.
