White-faced Nunbird
Hapaloptila castanea
Rare and elusive denizen of Andean cloud forest; found at higher elevations than any other puffbird. Distinctive; note especially the stout, black bill bordered by white feathers, chestnut underparts, and red eye. Found inside forest, often near exposed earthen banks, which they favor as nesting sites. Remains motionless for extended periods before suddenly sallying out to catch an insect or other small animal. Typical song is a series of evenly spaced, mellow whistles that can be imitated.
Ecuadorian Trogon
Trogon mesurus
Large, red-bellied trogon found only in western Ecuador and northwestern Peru. Both sexes have white eyes, plain black tail, mostly yellow bill, and a variable amount of white on breast. Male is mostly green with a black face. Female is mostly gray with a dark top to her yellow bill. Very similar to Blue-tailed Trogon, but usually shows a white spot or stripe on breast, and prefers dry and semi-humid forest. No overlap with Black-tailed Trogon. Perches on tree branches for long periods, occasionally sallying out to take fruits or insects. Song is a leisurely series of whistles or hoots.
Flame-rumped Tanager
Ramphocelus flammigerus
Fairly large tanager found in open habitats in lowlands and foothills below 1,500 m. Male is all black with contrasting rump varying from lemon yellow to red. Female is dark blackish-brown above and yellow below, sometimes with an orange breast band. She also has a contrasting rump varying from lemon yellow to red. On both sexes, note stout silver bill with dark tip. Common and conspicuous in clearings, gardens, shrubby areas, and second growth, usually in pairs or small groups.
