White-faced Quail-Dove
Zentrygon albifacies
Fairly large but elusive dove of humid evergreen and pine-evergreen forests in the highlands. It feeds mainly on the forest floor and may be seen beside quiet trails early and late in the day either walking quickly away or flushing explosively from close range. Heard much more often than seen. Rusty brown overall with blue-gray crown and whitish face. It Lacks the white tail corners of the smaller and grayer White-tipped Dove and is much larger than the male Ruddy Quail-Dove, with a different head pattern.

行为
The white-faced quail-dove forages singly or in pairs while walking on the ground, where it tends to favor dense cover. Its diet has not been documented but is assumed to be seeds, fallen fruits, and maybe insects.<p>The white-faced quail-dove roosts above the ground. It typically walks along branches or hops up to the roost rather than flying. Up to eight birds have been observed roosting together.<p>The whte-faced quail-dove's breeding season appears to vary within its range but has not been studied. Nests are loosely constructed of sticks and placed where they are well concealed, as high as 6 m (20 ft) above ground. The clutch size is two.<p>The white-faced quail-dove's song is "a low, hollow, mournful whoooo or whoo'oo."

Jelski's Black-Tyrant
Knipolegus signatus
Rare flycatcher found in cloud forest along the east slope of the Andes in northern and central Peru, barely reaching over the border into southeastern Ecuador. Male is dark sooty gray; female is grayish-olive with pale wingbars and faint streaking below. Similar to White-winged Black-Tyrant, but male Jelski’s is grayer and lacks white in the wings (which is usually only evident in flight) and female Jelski’s is much darker, especially on the underparts. No overlap with Plumbeous Black-Tyrant.
Cape Verde Swift
Apus alexandri
Small endemic swift of Cape Verde. Smaller and more gray-brown compared to other swifts, with prominent whitish throat patch. Note shallow forked tail. Flight faster and more fluttering than Common Swift and the closely-related Plain Swift. Calls very similar to Common Swift, but slightly higher-pitched.
Red-billed Partridge
Arborophila rubrirostris
Found throughout the highland forests of Sumatra (900-2500 meters), this small partridge’s bright red bill is unique in its range. Also note its reddish-brown chest, scaly black-and-white flank feathers, black-and-brown-striped back. Head pattern varies; can be predominantly black with white speckling or predominantly white with black crown and nape. Song is a rising series of whistles, some of which have a doubled quality: “wuew, wuwuew, wuew.” Like other Arborophila partridges, pairs often duet, with one bird giving the rising whistle song and another giving a series of lower “ooh” notes.
