Sula Scops-Owl
Otus sulaensis
A small brown owl with indistinct ear tufts (often not visible) and yellow irises. Largely brown, mottled with dark streaks and markings over much of the body, with pale and white markings on the wings. Inhabits forest and trees within swamps, mainly in the lowlands, but sometimes into the hills too. Distinctive: restricted to the Sula Islands, where it is the only small brown owl. Song is a tremulous, trill-like whistle repeated in quick succession (“brew-ooo”). Also gives a high shrill screech note.

Tumbes Hummingbird
Thaumasius baeri
A plain hummingbird found in dry forest and scrub in southwestern Ecuador and northwestern Peru. It is dull green with light gray underparts, a white spot behind the eye, and a thick, slightly curved bill. Some birds show very faint spots on the throat. Similar to Spot-throated Hummingbird, but throat markings are much less conspicuous or entirely absent. Ranges are also different; Tumbes Hummingbird is found only on the Pacific side of the Andes and does not reach the Marañon drainage.

Black-headed Sibia
Heterophasia desgodinsi
Somewhat recalling a darker, smaller Azure-winged Magpie, this medium-sized babbler is found in foothill to montane forests from central China to far southern Vietnam. Generally one of the most common birds in pristine hill forest throughout much of its range, and often a main component of mixed flocks. Typically moves through the canopy, though may descend lower, even occasionally to the ground when foraging.

Sumatran Green-Pigeon
Treron oxyurus
Relatively plain and unmarked green-pigeon with a long pointed tail. Males have a faint orange blush on the chest, though this can be hard to notice. Note blue-green bill and “goggles” in both sexes. Completely unmarked dark olive-green wings separate this species from other green-pigeons within its range; Wedge-tailed Green-Pigeon can be similar, but note that species’ much more thickset build and shorter tail. Endemic to the hill forests of Sumatra and western Java. Like other green-pigeons, gathers in fruiting trees. Gives rising and falling series of high-pitched coos, often with a hiccuping or sobbing quality.
