White-bellied Antbird
Myrmeciza longipes
Medium-sized antbird with a disjunct range from Panama to Brazil. Variable plumage across range. Male generally rufous above and gray below with a white lower belly and blackish face and throat.

识别特征
This antbird, like others in its family, is a forest bird with a preference for undergrowth in dry or moist deciduous habitats. It is a resident breeder which lays two or three eggs in a nest in a tree, both sexes incubating.<p>The white-bellied antbird is typically 15 cm long, and weighs 26 g. It has rufous brown upperparts and whitish underparts shading to cinnamon-buff on the flanks and lower belly. There is a long grey supercilium. The pink legs are long and strong, reflecting this bird's terrestrial lifestyle.<p>The male has a black face, throat and upper breast. The female has a darker crown, grey cheek patches and small dark spots on the wings, and lacks the black markings of the male. The northern race griseopectus has black spots on the wings and grey central underparts in both sexes.<p>The white-bellied antbird is an insectivore which feeds on ants and other arthropods at or near the ground; it sometimes follows columns of army ants. It may be located by its bright descending jeer-jeer-jeer-jeer-jeer-jeer-jeer-jeer-jeer-jeer-jeer-jeer song, which ends with a few chew notes.
分类信息
The white-bellied antbird was described by the English naturalist William John Swainson in 1825 and given the binomial name Drymophila longipes. The genus Myrmeciza was erected by the English zoologist George Robert Gray in 1841 with the white-bellied antbird as the type species. The genus formerly included more than 20 species. A molecular phylogenetic study published in 2013 found that Myrmeciza, as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera, the species formerly placed in Myrmeciza were moved to 12 other genera leaving the white-bellied antbird as only the only member of the genus.<p>There are four subspecies:

Javan White-eye
Zosterops flavus
Little bright yellow bird found in southern Borneo and northern Java. Entirely yellow coloration (no dark lores or gray belly) distinguishes this species from other white-eyes within its range. A coastal forest specialist, found in coastal scrub forest, mangroves, and forest edge, as well as adjacent gardens and plantations, where it often visits planted langsat (or duku) trees. Often found on small offshore islands. Forages actively in the canopy, giving quiet tweeting and cheeping calls; unlike other white-eyes, not a strong songster. Declining across much of range due to habitat destruction and fragmentation.
Black Francolin
Francolinus francolinus
Strikingly patterned male is unmistakable with his jet-black face and breast, white cheek patch, dark rust-brown collar, and bright white spots. Brownish female has a small orange nape patch, pale throat, and dense black-and-white markings all over the body; compare with larger Gray Francolin. Occurs in dry grasslands, agricultural land, and weedy fields. Shier than other francolins; more often heard than seen. Usually solitary or in pairs. Male call is a peculiar, metallic-sounding “keek, keek, kek-ke-kek.” Native to Asia, from Turkey east to far eastern India and northern Myanmar; introduced to Hawaii.
