分类信息
The rufous-winged antshrike was described by the English naturalist William Swainson in 1825 and given its current binomial name Thamnophilus torquatus. It and the rufous-capped antshrike (T. ruficapillus) are sister species. The South American Classification Committee of the American Ornithological Society is considering a proposal to lump them as a single species.<p>The rufous-winged antshrike is monotypic.

It inhabits the understorey of cerrado and nearby semi-deciduous woodlands. It also inhabits brushy gallery forest and second growth such as overgrown pastures and plantations. In elevation it mostly occurs below 1,000 m (3,300 ft) but ranges as high as 1,750 m (5,700 ft).

Anjouan White-eye
Zosterops anjuanensis
A small, sharp-billed warbler-like bird. Note the yellow patches on the throat and undertail and the bold white spectacles around the eye. Common on the island of Anjouan in the Comoros in habitats with woody vegetation, including remnant forest patches, plantations, woodland, scrub, and gardens. Usually found in hyperactive flocks. In its small range, easily identified by the white spectacles. The most common calls are a high-pitched, rising rattle and a descending “chew” note, which is also the main component of the quiet, chatty song.
Spectacled Petrel
Procellaria conspicillata
Large, stocky, dark petrel. Look for the diagnostic pattern of white “spectacles” on the face. In flight, alternates slow wing beats with glides. Usually seen well offshore in relatively warm waters. Breeds only on Inaccessible Island. The closely-related White-chinned Petrel lacks the white face pattern.
Black-backed Woodpecker
Picoides arcticus
Dark woodpecker, inconspicuous and uncommon. Found in coniferous forests, often in recently burned areas or bogs with many dead trees. Distinctive habit of flaking bark off trees in search of grubs; behavior shared only with American Three-toed Woodpecker. Back entirely glossy black with faint white markings only on flight feathers. Head mostly black with white mustache stripe and throat. Barred flanks. Males show yellow cap; sexes otherwise alike. "Pick" call is short and has unique clicking tone unlike other woodpeckers. Drum is slow, speeding up at end. Does not visit bird feeders.
