Atlantic Plain-Xenops
Xenops minutus
Active small bird of humid tropical forest. Usually found singly, often moving with mixed-species feeding flocks. Clambers and climbs on small branches, twigs, and vines, mainly at middle to upper levels inside forest. Often hangs upside down like a chickadee. Note the bold white whisker mark, boldly patterned black-and-rusty wings and tail, and short, wedge-shaped bill. Compared to Streaked Xenops, note the general lack of streaking in Atlantic Plain. Song is a short, relatively slow, high-pitched series of upslurred squeaky notes.
识别特征
The white-throated xenops is about 12 cm (4.7 in) long and weighs about 10 to 13 g (0.35 to 0.46 oz). Its bill is wedge-shaped, fairly stubby, and slightly upturned. The sexes are alike and juveniles resemble adults. Adults have a conspicuous buff or whitish supercilium and a wide pure white malar stripe. Their upperparts are dull brown to rufous brown and unstreaked; their crown is darker and lightly streaked. Their tail is cinnamon with much black. Their wings are also cinnamon, with a wide tawny or ochraceous band on the flight feathers. Their throat is pale with little or no streaking. The rest of their underparts are plain dull grayish brown. Their iris is dark brown, their maxilla dull black, their mandible dull grayish white with a dark gray tip, and their legs and feet bluish gray.
分类信息
The white-throated xenops was formerly considered a subspecies of the plain xenops (now Xenops genibarbis, formerly X. minutus). HBW recognized the split by 2018 and the IOC followed suit in July 2023. However, the South American Classification Committee of the American Ornithological Society (SACC) and the Clements taxonomy retain it as a subspecies of the plain xenops. The SACC does state that Xenops minutus sensu lato might consist of more than one species.<p>The white-throated xenops is monotypic: No subspecies are recognized.

White-fronted Black-Chat
Oenanthe albifrons
A small and relatively slim black chat. There is some geographical variation: males can show a small white patch on the forehead, or a larger one that covers most of the crown. In some areas, males also have a white shoulder patch. Females vary from being completely black to having a gray throat and sometimes a gray forehead. Found in open savanna, often in rocky and/or recently burned areas. Similar to Sooty Chat and Northern Anteater-Chat, but smaller, and male can always be identified by the white forehead patch. The song is long, chatty, and musical.
Ferruginous Babbler
Pellorneum bicolor
Reddish-brown babbler with white underparts. General appearance resembles White-chested Babbler but much more warmly-colored. Forages in small flocks in the lower and middle levels of lowland and lower foothill forests. Gives a loud, explosive “chew-WIT!” and various chattering and rasping notes.
Australian Masked-Owl
Tyto novaehollandiae

Nests in a variety of habitats; requires hollows of very large trees for nest sites, and these may be in both drier and wetter forest types. Variable in size and color, ranging from larger, browner birds in Tasmania through to smaller, paler birds in northwestern Australia. This species is generally larger, darker, larger-legged, and more heavily spotted than Barn Owl. Call includes a loud explosive hiss.
