Gurney's Eagle

Aquila gurneyi

A large raptor which soars over lowland and foothill forest and disturbed areas. A dark, stately eagle with long wings, long tail, pale patches at the base of the flight feathers. The wings are held flat in flight and feathers are ‘fingered’ at the wing tips. Similar to Wedge-tailed Eagle, with which it doesn’t normally co-occur, but Gurney’s Eagle has a long, rounded tail rather than a wedge-shaped tail. Call described as a high-pitched downslurred note.

White-throated Rail

White-throated Rail

Dryolimnas cuvieri

A big, robust, rather colorful rail. The olive-green back, reddish underparts, and white throat are distinctive. Much less shy than typical rails, and sometimes quite tame. Found on the ground in forest, mangroves, moist scrub, marsh, and rice paddies. Quite vocal; most common call is a very loud, ringing series of rising “schweeet” notes. Larger than wood-rails, with a longer bill and a much larger white throat patch. Also larger than Madagascar Rail, with brighter coloration. 

Amazonian Black-throated Trogon

Amazonian Black-throated Trogon

Trogon rufus

Yellow-bellied trogon with pale blue or yellow eyering and yellowish bill. Male has shimmering green-blue upperparts and chest; female is brown. Underside of tail barred black and white with large white tips. Found in forested areas, usually sitting still at low to middle heights (often lower than other trogons in range). Male from Amazonian Trogon by head and chest color (greener, not deep blue), yellower bill, and voice. Brown color of female is distinctive, unlike slaty-gray of female Amazonian. Listen for song: a slow, evenly-spaced series of 3-6 slurred whistled notes.

Lowland Peltops

Lowland Peltops

Peltops blainvillii

A medium-sized bird of lowland forest edge and clearings. Distinctive plumage. Mainly black, bright red above and below the base of the tail, and white marks on the cheek and back. Perches in tall trees, sallying for flying insects. Very similar to Mountain Peltops, but Lowland is found at lower elevations and has a smaller white cheek. Voice, a double note rap, “plik-it!” repeated at regular intervals. Also, a distinctive, unbirdlike, vibrating rattle.
