Harlequin Antbird
Rhegmatorhina berlepschi
Striking antbird with a cinnamon breast band and a bare eyering. Males have gray underparts, while females have buff underparts scaled with black. Has a very small global range, occurring in the understory of humid forests, where it attends army-ant swarms. The song is a series of descending whistles ending with a harsh “chirr.”
识别特征
The harlequin antbird is 14 to 15 cm (5.5 to 5.9 in) long. Both sexes have a small crest and a pale grayish green ring of bare skin around the eye. Adult males have a dark brownish crown; their crest and nape are rufous-chestnut. Their upperparts, wings, and tail are olive-brown with rufous edges on the wing feathers. Their face and throat are black and their breast's center rufous-chestnut. The sides of their neck and the rest of their underparts are gray with an olive-brown tinge on the flanks. Adult females are similar to males with the addition of buff-edged black tips on their upperpart feathers and wing coverts and black and pale buff banding on their sides and lower breast.
分类信息

The harlequin antbird has a very limited range in Amazonian Brazil. It is bounded by the Amazon on the north, the Rio Madeira on the west, and the Rio Tapajós on the east. Its southern limit is indistinct. The species inhabits the understorey of humid terra firme evergreen forest. Its range is entirely below 100 m (300 ft) of elevation.

Nubian Bustard
Neotis nuba
Fairly large and lanky bustard. The face is boldly marked, with black throat and eyebrow patches and a rufous crown. These markings are fainter on females. In flight, shows a large white patch on the wings that is more extensive than those of other bustards in its range. A generally scarce and likely nomadic species that is found in dry savanna and semi-desert habitats of the Sahel. Similar to White-bellied Bustard, but larger and lankier, with a different head and neck pattern.

Crested Black-Tyrant
Knipolegus lophotes
Large flycatcher found in grasslands and savannas with scattered trees. Unmistakable by its uniform black plumage and long thin crest; sexes similar. In flight shows a white wing patch. Usually silent, but the song is sharp and nasal “djew-pew.”

Red-billed Scythebill
Campylorhamphus trochilirostris
Look for the notably long, extremely decurved bill. Otherwise a typical woodcreeper, mostly warm brown with buffy streaks on the head and breast. Easy to identify when the only scythebill in range, but does overlap with other scythebill species. Especially beware of Curve-billed Scythebill, which typically has less streaking on the back (but streaking is variable across range, hence some might be best left unidentified). Red-billed’s red bill is usually obvious enough to distinguish from Brown-billed Scythebill, but can be difficult to judge in certain conditions. Note Red-billed is often found in drier forest than Brown-billed. Hitches up tree trunks much like a woodpecker. Most often seen following mixed-species flocks in the forest, sometimes in adjacent second growth. Typically below 1,000 m, but locally higher.
