Tooth-billed Wren
Odontorchilus cinereus
Slender, inconspicuous wren with a long tail, recalling a gnatcatcher. Has rather dull plumage: gray above, very pale grayish below, with a brownish crown. Note the dark bars on the tail. Forages high in the canopy of humid forests and almost invariably accompanies mixed-species flocks. Sings a loud series of “tsee” notes repeated continually.
识别特征
The tooth-billed wren is 12 cm (4.7 in) long; one male weighed 11 g (0.39 oz). Adults have a grayish cinnamon crown, a grayish brown face, and a medium gray back. their throat and breast are buffy gray, the belly pale buff, and the flanks grayish white. The juvenile looks essentially the same.
分类信息
The tooth-billed wren shares its genus with one other species, the grey-mantled wren (Odontorchilus branickii). Some authors have suggested that they are conspecific or that they form a superspecies. The tooth-billed wren is monotypic.

分布与栖息地
The tooth-billed wren is found mostly in Brazil but its range extends slightly into Bolivia's Santa Cruz Department. It is found south of the Amazon River between the Madeira River on the west and the Xingú River on the east. It inhabits tall humid lowland forest at elevations up to 600 m (2,000 ft).

行为
The tooth-billed wren's diet is not known in detail, but the species is insectivorous. It forages in the canopy, 15 to 30 m (49 to 98 ft) above ground, exploring and probing the foliage along branches and in vine tangles. It usually is part of a mixed-species foraging flock.<p>The tooth-billed wren's breeding season appears to span from June to September based on dates when active nests, dependent juveniles, and physiological evidence have been observed. It nests in a cavity in a limb or trunk high above the ground. The clutch size is believed to be two.<p>The tooth-billed wren's typical song is "a short, simple trill" [1]; both sexes sing it.

Purple-throated Fruitcrow
Querula purpurata
Large, mostly black bird found in the canopy of lowland forests. Male has wine-colored throat that can be puffed out expressively, but is often difficult to see in poor light. The overall dark color, stout silvery bill, and chunky proportions help identify this bird even at a distance. Also listen for the distinctive purring whistles, “prr-woop, prr-woop.” Typically found in small vocal groups that parade through the canopy, sometimes following mixed-species flocks. Compare with umbrellabirds, which are larger, have a puffy crest, and are much less vocal.
White-headed Bulbul
Hypsipetes thompsoni
Unmistakable gray bulbul with a striking white head, rose-red bill, and orange vent. Passingly similar to white-headed forms of unrelated Black Bulbul but lacks shaggy crest, dark vent, and inky-black body of that species. Gives harsh, chattering, somewhat parrot-like calls while flocking. Song is a repetitive and squeaky series of distinct two-note phrases. Breeds in foothills and montane areas, preferring open forests and forest edges. Descends into foothills and lowlands during non-breeding season.
Black Scrub-Robin
Cercotrichas podobe
A unique and unmistakable passerine. Large and dark with a magnificent white-patterned tail that it often holds up. Spends much time on the ground or on low branches. In flight shows a rusty wing pattern. Favors dense scrub in arid zones. Variable song is sweet and melodious, often including trills and rattles. Calls include a pleasant, descending “jweeee” and chattering notes.
