Sierra Madre Ground-Warbler

Emerald green hummingbird found in humid forest in lowlands and foothills of northwestern Ecuador and western Colombia. Note, especially, the white vent. Male has bluish-purple patch on breast, which is reduced or lacking in female. Both sexes quite similar to Blue-chested hummingbird but can be distinguished by the contrasting white vent. Usually encountered at forest edge or in clearings, and visits feeders in a few places.

A medium-sized greenbul of thickets and tangles that prefers edge and semi-disturbed habitats. Most often seen in pairs or small family groups, but it will occasionally join other species in flocks. Gray below except for a bright yellow throat, and uniformly yellow-green above with reddish eyes. Most likely to be confused with the similarly named Yellow-throated Greenbul, which usually has a paler whitish throat in areas where the two species overlap. Yellow-necked Greenbuls can be distinguished by their uniformly gray underparts, brighter olive-green upperparts, dark red eyes, and consistently bright yellow throats. Voice is a variable subdued chatter, “kur-ku-kurkwu.”

Fairly large trogon of pine and pine-oak forests in highlands; usually at upper levels in trees and often rather shy. Male is striking, with big, bold white squares on underside of tail. Female has broken white eyering on brown head and coarse black-and-white pattern under the tail. Elegant Trogon overlaps in range and can be told from Mountain by the coppery color on the top of the tail (male) or by the white stripe behind the eye (female). Also note the finely patterned tail on both male and female Elegant Trogons. The similar but smaller Collared Trogon is found mainly at lower elevation and has much finer barring on the underside of the tail.
