Rufous-faced Crake

Rufirallus xenopterus

Very secretive crake with a relatively long tail and a stout bill. Note the rufous neck and crown that contrast with a black back, the thinly barred black-and-white sides, and the white belly. Inhabits shallow flooded marshes with tussocky or matted grasses. Compare with Red-and-White Crake, which lacks barred wings and has a white (not black) vent, a yellowish (not gray) bill, and gray (not red) legs. Song is a long descending trill.

分布与栖息地

The rufous-faced crake is found in northeastern Bolivia's Beni Department, in several states in south-central Brazil, and in central Paraguay. It is known from perhaps a dozen widely scattered locations in those areas but "given the suitable habitat in intervening areas and elsewhere[...]the species may be more widespread and less local than suspected." It inhabits marshes, especially the zones of moist to shallowly flooded tussocky or matted grass.

Western Black-eared Wheatear

Western Black-eared Wheatear

Oenanthe hispanica

A small, slim wheatear. Males striking: black wings contrast with a yellowish back and crown and a black mask through the eye. Throat can be white or black. Females have a more muted version of the male’s overall pattern. The tail has a complicated black-and-white pattern that is conspicuous in flight. Found in open habitats with scattered trees, including savanna, rocky mountain slopes, and barren pastures. Very similar to Eastern Black-eared Wheatear, but usually distinguished by more extensive and warmer yellow wash on the head, back, and breast. Also similar to Pied Wheatear, but male’s black face patch is not connected to the black wing, and female is warmer and browner than the grayish female Pied. Call is a dry, hoarse “chercher.” Song is a short jumble of primarily descending trills and harsher notes.

White-winged Black-Tit

White-winged Black-Tit

Melaniparus leucomelas

A black tit with a mostly white wing and a white outer tail. Found in moister types of savanna, both broadleaf and thorny. Usually in pairs or small groups which are loud and conspicuous. Call is a classic tit “chee-chi-chi-chi-chi,” raspy and often repeated. The song consists of wispy, musical, up-and-down whistles. Very similar to White-shouldered Black-Tit, and best separated by the dark, rather than yellow, eyes.

Chestnut-crowned Gnateater

Chestnut-crowned Gnateater

Conopophaga castaneiceps

Plump, short-tailed bird of Andean cloud forest understory. Male is gray with a chestnut crown and brownish-tinged back. Female is browner with chestnut extending to neck and breast. Both sexes have a partially concealed white plume behind eye that can be lifted when the bird is excited. Usually encountered alone and perched near the ground. Song is a harsh, staccato rattle that rises in pitch.
