Wedge-tailed Grass-Finch
Emberizoides herbicola
Among all the streaky sparrowlike birds of open grassy habitats in its range, Wedge-tailed Grass-Finch is unique with its long spiky tail. Also note the stout yellow bill. Otherwise rather pale brown overall, clean buffy below with thick black streaks on back. If seen well, back and wings are suffused with a yellow tone. Similar to Lesser Grass-Finch, but is larger, darker and lacks a white throat. Look for singles or pairs in grassy or brushy fields, often announcing their presence with a chip note.
Green-tailed Jacamar
Galbula galbula
Distinctive, energetic bird of secondary forest, river edges, and disturbed habitats. Note iridescent green plumage with rusty belly, long pointed bill, and active behavior. Often found in pairs or small groups within a few meters of the ground. Feeds on flying insects, which it catches in mid-air from a prominent perch; often returns to same perch to dispatch and consume prey. Frequently gives loud, squeaking call.
Bare-cheeked Trogon
Apaloderma aequatoriale
A trogon of lowland rainforests, almost always found in the forest interior, away from forest edges. Males and females have distinctive bare yellow facial skin below their eyes and between their eyes and bill. Both sexes have green backs and uppertails, red chests and vents, and finely barred wings. The species often calls motionless in the subcanopy, giving a series of 6-10 sad, descending coo notes, repeating these series 2-3 times per minute. Similar to the larger Narina Trogon, but Bare-cheeked Trogon is told apart by its song, its closed-canopy forest habitat, and the purely green tones on its head, back, and uppertail.
