Inambari Woodcreeper

The Inambari woodcreeper is 17 to 19 cm (6.7 to 7.5 in) long and weighs about 31 to 35 g (1.1 to 1.2 oz). It is a smallish, slim, woodcreeper with a slim decurved bill. The sexes have the same plumage. Adults' face, crown, and nape are dark russet-brown with few or no spots on the crown. Their back and wing coverts are dark russet-brown, and their rump, wings, and tail rufous-chestnut with dusky tips on the primaries. Their throat is plain buffy. Their breast and belly are grayish brown to olive-brown with bold, brownish-edged, buff to creamy white streaks. Juveniles have darker upperparts than adults, a grayer crown with some spots, and whiter, somewhat reduced, streaks on the underparts.

The Inambari woodcreeper is found in western Amazon Basin of eastern Peru, northern and central Bolivia, and western Brazil south of the Amazon River as far east as the Madeira River. It mostly inhabits terra firme and floodplain forest. It occurs less often in swamp forest and flooded várzea forest, and in shade coffee plantations in Peru. It favors the interior and edges of tall primary forest and mature secondary forest and is found only rarely in younger secondary forest. It elevation it seldom exceeds 1,000 m (3,300 ft) though it has reached 2,225 m (7,300 ft) in the Peruvian Andes.

The Inambari woodcreeper's diet is primarily arthropods. It usually forages singly or in pairs, and often joins mixed-species feeding flocks. It hitches along branches, often on their underside, mostly in the forest's sub-canopy and canopy, occasionally in the middle levels, and rarely if ever in the understory. It takes most of its prey from bark, by picking, probing, and prying off flakes. It also sometimes probes vegetation like epiphytes but only infrequently sallies after airborne prey.
