Scarlet-rumped Tanager
Ramphocelus passerinii
Fairly common in humid tropical lowlands. Favors evergreen forest edges, plantations, and verdant second growth, such as areas along roadsides. Forages mainly at low to middle levels often in fairly noisy small groups. Male is unmistakable if seen clearly: velvety black with a blinding scarlet rump. Female is very different: note distinctive bluish-white bill, tawny rump, and grayish head. Formerly known as Cherrie's Tanager and Passerini's Tanager.
识别特征
The adult Scarlet-rumped tanager is 16 cm long and weighs 31 g. The adult male is mainly black except for a scarlet rump, silvery bill and dark red iris. The female has a grey head, olive upperparts becoming brighter and paler on the rump, brownish wings and tail and ochre underparts. The female's plumage is the one that differs most from Cherrie's tanager. Immatures have an orange tint to the underparts and rump, and look like a paler and duller female Cherrie's tanager.<p>The Passerini's tanager's call is a sharp wac. Its song consists of a few clear pleasant notes, delivered in shorter phrases than that of its Pacific relative.

This species feeds on certain small fruit, usually swallowed whole, insects and spiders.<p>The cup nest is built up to 6 m high in a tree.

Cock-tailed Tyrant
Alectrurus tricolor
A remarkable flycatcher; males are black above and white below with a broad tail that has longer central feathers and is usually held perpendicular to the others and spread like a fan. Females are mottled brown above and whitish below without the cocked tail. Occurs in open, humid, and tall grass savanna areas that have been well preserved. Mostly silent.
Spotted Ground-Thrush
Geokichla guttata
Large brown-backed thrush with heavy spotting below and white wingbars. It is a rare and localized endangered species, with most records coming from a few coastal and montane forest sites. Usually on or near the ground. The song is a languid, chatty series of whistles. The call is a quiet, thin, rising whistle. Similar to Groundscraper Thrush, but easily separated by forest habitat, more horizontal posture, and white wingbars.
Black-billed Sicklebill
Drepanornis albertisi
A large, long-billed bird of mid-montane forest. Brown upperparts and grayish, facial skin behind the eye. Note the curved, black bill. Male has a black throat and a small, hornlike tuft in front of each eye with blue-green iridescence. Female has pale underparts with dark scaling. Uses its distinctive bill to probe for insects but also takes fruit. Female similar to female Black and Brown Sicklebills, but usually occurs at lower elevations, has a shorter tail and lacks the black throat. Song, a series of identical high notes, slurred into a loose trill which increases in volume.
