White-eared Puffbird
Nystalus chacuru
A familiar species of relatively dry savanna, scrub, and forest edges announcing its presence with a loud whistled song. Notable for its strong and thick orange bill with a dark tip, and the large white cheek patch. Typically found in pairs, perching on exposed branches.
识别特征
Like some other puffbirds, the white-eared puffbird is a round, plump bird with a very narrow tail. The head is relatively large, with a dark brown barred crown, and an orange, black-tipped bill. The sit-and-wait feeding strategy, for insects or opportunistic prey, may explain this body shape.<p>The bird has a medium-brown back and wings, with dark rufous speckles and bars; white and black flecked on the breast. The upper breast is white, extending to a narrow-to-medium white collar around the neck. There is a distinctive, medium-sized white ear patch, which gives the species its common name, and that is surrounded by a dark ear patch. It has a medium-sized tail in dark brown and slightly graduated, with narrow, widely spaced buffy bars, and a pale tip. It measures about 21–22 cm (8.3–8.7 in) in length and weighs between 48–64 g.

分布与栖息地
The white-eared puffbird can be found from eastern Peru and central Brazil south to Paraguay, Bolivia and northeastern Argentina.<p>In south-eastern Brazil, it is centered on the Cerrado region, and on the southeast Atlantic coast from northern Bahia state south to the Paraná–Santa Catarina state borders. It covers much of the eastern and northern Pantanal, and southern areas of the Caatinga.<p>The north and west parts of its range include the upstream headwaters of some Amazon Basin river systems, encompassing nearly all of northern Bolivia, the Madeira River's many headwater tributaries, and the extreme headwaters of the Tapajós River. East of the Tapajós, the range expands into the Cerrado, the upper half of the Xingu River drainage, and the entire drainage system of the Araguaia-Tocantins River (the eastward system, generally considered part of the Amazon Basin).<p>In Peru, the species is rare but local, found on the very western border region of Bolivia and in some localities in north-central Peru. In this region, it favors the dry forests and scrub found in parts of the Valleys of Mantaro, Apurimac and Urubamba at altitudes between 1000 and 2200 m. It was also recorded in the Mayo Valley.<p>Another second locale is mid-river on the downstream Madeira River in southern Amazon Basin Amazonas state.

Hartert's Leaf Warbler
Phylloscopus goodsoni
Bright yellowish leaf warbler of forest canopy. Like Blyth’s and Claudia’s leaf warblers, Hartert’s has the habit of flicking its wings alternately; compare to Kloss’s and Davison’s leaf warblers, which flick both wings at the same time. Bright olive above with a broad yellow brow and yellow-suffused white belly. Crown stripe and broad, orange-based bill distinguish this species from the similarly sized and shaped Arctic Warbler and Pale-legged Leaf Warbler. Breeds in foothill and submontane broadleaf forests, winters in various wooded habitats at lower elevations, including forest edge. Song is a sweet, high-pitched “wit-wichichew-wichichew-wichichew.” Call is a quiet “wit” or “wichichew.”
Painted Stork
Mycteria leucocephala
A large stork with a long yellow bill that curves down at the tip, like that of an Ibis. Adult is primarily white with black striped markings on the wings and bright pink on tertials. Also note the bright orange face, pinkish legs, and speckled band across the chest. Immatures are duller, with a brown wash, and lack the chest band. These storks typically fly with their head and neck drooping almost at or below the belly level. Often seen near water bodies such as wetlands, marshes, and flooded agricultural fields. Breeds in crowded colonies, often with other waterbirds.
Black-nest Swiftlet
Aerodramus maximus
A small dark Aerodramus swiftlet that is nearly impossible to distinguish from closely-related species such as Mossy-nest and White-nest Swiftlets. Dark above and paler gray below; rump varies from dirty white to dark depending on subspecies. Tail averages more squared-off and less prominently forked than White-nest and Germain’s swiftlets, but best identified when on feather-and-saliva nests, which are dark, as the name suggests. Nests in large colonies in caves, often with other species of swiftlet. Chitters at nest, but usually fairly quiet.
