Myiopagis olallai
The Foothill Elaenia (Myiopagis olallai) is a small, rather unassuming tyrant flycatcher, measuring approximately 12-13.5 cm in length and weighing 10-12.5 grams. Its plumage features olive-green upperparts, head, and nape, contrasted with pale yellow underparts, often with a subtle greenish wash on the breast and flanks. Distinctive field marks include two prominent yellowish-white wing-bars and sometimes a faint whitish supercilium and pale eye-ring. While generally drab, it possesses a hid...
Found in humid montane forests, cloud forests, and forest borders, primarily at elevations between 900 to 2,000 meters.

The Foothill Elaenia resides along the humid eastern slopes of the Andes, extending from central Colombia south through Ecuador and Peru, and reaching into western Bolivia. Its distribution is generally continuous within this altitudinal band, typically from 900 to 2,000 meters, though occasional...
