Dark Batis
Batis crypta
Males have the typical batis pattern of black, white, and gray. Females have a more unusual pattern, with rufous in the wing, rufous on the throat, and a variable amount of rufous on the breast. Both sexes have orange or reddish eyes. Found at middle levels and in the canopy of forest at low and middle elevations, often in pairs. Very similar to Short-tailed Batis, but there is no known overlap in range. Males are similar to Chinspot and Pale Batises, but are distinguished by the darker eye and shorter tail. Females are distinctive. The song is variable, but is usually a long, slow series of identical low-pitched tooting notes, sometimes given along with raspy “chugaree” calls.
Identification
The dark batis is about 10 cm (3.9 in) in length and weighs 10–15 g (0.35–0.53 oz). It has a dark bill and legs and red eyes. The male is white below with a broad black breastband. Above it has a dark grey crown, grey back with some black feather-tips, a black face-mask and black wings with a white stripe. The female has a greyish crown, brownish back, dark mask, slight white supercilium and a narrow rufous stripe on the wing. Below it has a rufous chin-spot and breast with whitish tips to some of the feathers.<p>The forest batis has a slightly shorter tail. Males of the two species are very similar but forest batises have a narrower breastband and usually some hint of a white supercilium which is lacking in the male dark batis. The females are more distinctive: female forest batises have a paler breast and chin with more white tips giving a mottled appearance. There is a conspicuous white supercilium and a broad rufous wing-stripe.<p>The dark batis has a variety of whistling and harsh churring calls and its wings make a whirring sound in flight. The male's song is a series of short, low whistles.

Ancient Antwren
Herpsilochmus gentryi
This antwren is known only from a small area in northeastern Peru and adjacent border areas of Ecuador. It is confined to rainforest that grows in nutrient-poor soils with a specific mineral composition. Note the yellowish underparts, black crown and black eye-stripe separated by a pale eyebrow, and bold white wingbars and tail edges. Similar to Dugand’s Antwren, but male has yellowish underparts and female has a black (not brown) crown. Stays quite high in the trees and often joins mixed-species flocks. Song is decelerating series of notes that rises and then falls.
Tahiti Swiftlet
Aerodramus leucophaeus
A medium-sized swiftlet with a relatively long forked tail. Mostly brown with very slightly paler brown underparts and a more golden-brown rump. Most common over rocky riverine valleys and humid forests. Similar to Atiu Swiftlet but is less contrastingly patterned, overall more uniformly brown, with a paler rump and a proportionally longer tail. Also extremely similar to Marquesan Swiftlet, but appears paler-faced and lacks a pale collar. Call is an insect-like buzzing and trilling.
Line-cheeked Spinetail
Cranioleuca antisiensis
Handsome spinetail of Andean forest and scrub; ranges from southern Ecuador to central Peru. Plumage is grayish-brown with a white eyebrow and bright chestnut crown, wings, and tail. Birds in Ecuador and far northern Peru are slightly smaller and tend to be browner, with a bit less white on the throat. Typically found in pairs at any level, and often quite vocal. Typical song is a few sharp squeaks followed by a descending trill.
