Black Coucal
Centropus grillii
Small coucal of marshes, swamps, and wet grassland. Distinctive in breeding plumage: black with a rufous wing. In non-breeding plumage, buffy and streaked. Skulks in the undergrowth, occasionally emerging to sit on an exposed perch. Vocalizations are a two part “kuu-kuk” and a descending and accelerating series of “tow” notes. In non-breeding plumage, separated from White-browed and immature Senegal coucals by its slightly smaller size and lack of a white eye stripe.
Identification
The male black coucal is 30 cm (12 in) in length while the female is 34 cm (13 in), otherwise they are similar in appearance. In breeding plumage the head, body and tail are black, apart from some buff barring on the rump, and the wings are rufous. Outside the breeding season, the upper parts are dark brown with rufous barring. The eyes are brown and the beak and legs are black. Juveniles are rufous with various dark and light barring and streaking.

Other Birds
Violet-throated Metaltail
Metallura baroni
High-elevation hummingbird endemic to the Andes of southern Ecuador. Plumage is mostly green with a purple throat, and tail is blue on top and greenish underneath. Bill is short and straight. Female has underparts scaled with gray or buff. Compared to the common and widespread Tyrian Metaltail, Violet-throated lacks a rusty tail and has a purple (not green or buffy) throat. Inhabits montane scrub and edge of stunted forest. Most sightings come from in and around Cajas National Park.
White-winged Woodpecker
Dendrocopos leucopterus
Large black-and-white woodpecker; very similar to Great Spotted Woodpecker, but with a single large and rather formless white patch dominating the entire wing instead of scattered white dots and bars. Found in waterside clusters of forest, preferring poplar stands, in the largely dry and treeless expanses of Central Asia.
Louisiade Fantail
Rhipidura louisiadensis
Small, active songbird with long, pale-tipped tail and warm brownish-orange on the forehead, rump, and tail base. Grayish brown above and pale below overall, with a white throat and black-speckled breast. Frequently cocks and fans tail. Endemic to the D’Entrecasteaux and Louisiade Arcipelagos, off southeastern New Guinea, where inhabits wooded areas, particularly on small offshore islets. Listen for high-pitched, tinkling song. Formerly grouped with other closely related species under “Rufous Fantail.”
