Bare-eyed Antbird

Fantastic-looking antbird with a bold whitish bare eye-ring and a restricted range. Males have a black head and breast, and are otherwise cinnamon-brown; females are duller around the head, but otherwise also cinnamon.

分布与栖息地
The bare-eyed antbird has a limited range in southeastern Amazonian Brazil. It is bounded by the Amazon on the north, the Rio Tapajós on the west, and the Rio Xingu on the east. Its southern border is not well known but extends at least to the Teles Pires in northern Mato Grosso state. The species almost entirely inhabits the understorey of very humid terra firme primary rainforest, though it has also been recorded in várzea. Its range is entirely below 400 m (1,300 ft) of elevation.

Javan Banded-Pitta
Hydrornis guajanus
Beautiful ground-dweller with black mask, clean white throat, and finely barred underparts. Male has an egg-yolk-yellow eyebrow, royal-blue “bib”, and black crown. Female has a dull tan-yellow eyebrow and brown crown. Both sexes have a bright blue tail and a white “racing stripe” down the edge of the wing. Inhabits a range of wooded habitats, from primary wet forest to overgrown plantations and dry scrub, in the lowlands and foothills of Java and Bali. Forages on the ground, either singly or in pairs. Gives a loud, bright “whOW!” and a low rolling trill.
Yellow-billed Spoonbill
Platalea flavipes
Large dull-white bird with a long, spoon-shaped bill. Plumage often appears dirty. Diagnostic yellow facial skin, legs, and bill. Feeds singly or in small flocks. Submerges bill and makes a sweeping motion to capture prey. Found in a wide variety of freshwater habitats; rarely in marine environments.
Green-and-black Fruiteater
Pipreola riefferii
Chunky, short-tailed, flat-headed bird patterned in green and black. Male has black head and breast, yellow belly with messy green streaks, and green upperparts. Female is almost all green. On both sexes, note red bill and legs and dark eye. Fairly common in forested habitats in the subtropical and temperate zone. Perches quietly in the middle levels of the forest, often following a mixed-species flock. Usually in pairs, but several can gather around a fruiting tree. Listen for super-high-pitched song, a series of tinkling notes sometimes followed by a long, thin “seeee.”
