Bahia Tapaculo
Eleoscytalopus psychopompus
Small, retiring bird, gray above and white below with an unbarred cinnamon vent. Occurs in a few remaining fragments of humid forest with dense understory, often near water, across a very restricted range. The song is a low trill, repeated continually.
识别特征
Until the 1990s the Bahia tapaculo was known from only three specimens. Surveys targeting it have resulted in sight, photographic, and audio records since then. Based on the specimens, the white-breasted tapaculo is 11 cm (4.3 in) long. One male weighed 17.5 g (0.62 oz) and one female18 g (0.63 oz). The adult's upper parts are blue-gray and its rump reddish brown. The throat, chest, and belly are white and the flanks and vent area are chestnut without the barring that the very similar white-breasted tapaculo has.
分类信息
The Bahia tapaculo and the white-breasted tapaculo (Eleoscytalopus indigoticus) were formerly placed in the genus Scytalopus, but these two species are now known to be more closely related to the bristlefronts (genus Merulaxis). The Bahia tapaculo has also been proposed as a race of the white-breasted tapaculo, but genetic data refute that.

行为
Nothing is known about the Bahia tapaculo's diet or feeding habits. The only data related to breeding is that a male and female collected in October 1983 had active gonads. The song is a trill up to four seconds long that increases in volume after the first one or two seconds [1].

Brown-headed Thrush
Turdus chrysolaus
A large migratory thrush, breeding in northern Japan; a wintering bird in Taiwan and elsewhere. All plumages rich earthy brown above, with extensive orange sides and white central bellies. Male has sooty brown throat and cheeks, female and young birds streaked throats and faint supercilium. Found mostly in forests but also ventures into fields and gardens in winter.
Buff-collared Nightjar
Antrostomus ridgwayi
Fairly large, rather pale grayish nightjar of scrubby woodlands, thorn forests, edges and adjacent clearings in western Mexico. Hunts mainly from perches at forest edge and from the ground. Cryptic plumage similar to other nightjars; both sexes have buffy collar on the back of the neck. Male has white tail corners. Female has narrow, pale buffy tail corners. Best detected and identified by voice: striking song is a rapid, accelerating series of hollow clucks ending with an emphatic “chee-aa.”
White-throated Babbler
Argya gularis
Rich chestnut-brown babbler with a bright white throat and chest. Inhabits dry scrubby areas, often fairly close to human habitation. Like other babblers, fairly social, gathering in small bands; birds often give a fairly high-pitched rolling chatter as they forage together.
