Inambari Woodcreeper
Lepidocolaptes fatimalimae
Fairly small woodcreeper with a thin, slightly downcurved bill. Extensive streaking on the undersides but almost no streaking on the head or back; when viewed from the back, appears very plain. Olive-brown back and head, often noticeably slightly greener than the rest of the bird. Found mostly in secondary forest, with tall trees and a dense understory. Its song is a descending series of fast whistles, recalling the longer song of White-browed Antbird, or for some, the call of Downy Woodpecker.
Identification
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.
Taxonomy
The Inambari woodcreeper was described in 2013 as part of the reevaluation of Lepidocolaptes albolineatus, which was then called the lineated woodcreeper. Starting in the early 2010s, all but the lineated's nominate subspecies were split from it, eventually resulting in recognition of the Inambari woodcreeper (which had not been known as a subspecies), the Duida woodcreeper (L. duidae), the dusky-capped woodcreeper (L. fuscicapillus), and a monotypic L. albolineatus which was renamed the Guianan woodcreeper.<p>The Inambari woodcreeper's specific epithet honors Fátima Lima, manager of bird collections at the Museu Paraense Emílio Goeldi.<p>The Inambari woodcreeper is monotypic.

Range and habitat
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.

Behavior
The Inambari woodcreeper is believed to be a year-round resident throughout its range.<p>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.<p>Little is known about the Inambari woodcreeper's breeding biology. Its breeding season seems to include late July to early August. It nests in cavities in trees. One nest contained two eggs.<p>The Inambari woodcreeper's song differs from those of its former conspecifics; their songs were among the strongest evidence for their separation. Its song is "a soft trill comprising 16–37 notes (typically 26–33), like that of a becard (Pachyramphus) that trails off at end".

Mountain Buzzard
Buteo oreophilus
Medium-sized brown raptor of montane habitats. Shows thick dark brown streaking on the underparts. In flight, the underside of the wing is streaked brown at the front and solidly white at the back, with a rim of black. Found in mountain forest and adjacent open habitats. Often soars. The call is a piercing whistle. Very similar to the migratory Common Buzzard, but never shows red in the tail, and always has a pattern of heavy dark brown streaks below.
Red-faced Guan
Penelope dabbenei
Mostly arboreal guan endemic to the semi-humid forest with Podocarpus and alders of the mid-elevation east Andes in southern Bolivia and northeast Argentina. Often in ravines and river basins. The sympatric Dusky-legged Guan is more common, but shows grayish-blue skin around the eye. Tends to perch high in trees, singly or in pairs, and often found by far-carrying vocalizations given from high in trees. Note pale supercilium, dull pinkish legs, exposed red orbital skin and wattle.
Sickle-winged Nightjar
Eleothreptus anomalus
While perched, appears to be an unassuming nightjar: rather small, short-tailed, and largely gray with dark brown spots. In flight, males are spectacular, with unique flight feathers forming the “sickle” wing shape. Females lack these modified wing feathers. Usually found close to water, around gallery forest; in some areas also in grassland and marshes. The call is a repetition of very subtle “chip” notes.
