White-lined Antbird

Reddish-brown wren with a faint pale eyebrow found in the understory of humid montane forest. Larger and longer-tailed than the tiny Mountain Wren, which also has a bolder eyebrow. Replaced at the northern end of its range by the very similar Peruvian Wren. Forages singly or in pairs low in bushes and near the ground. Listen for its loud song, a flowing series of whistles and trills.

A very small nondescript sunbird with a short orange-based bill that curves uniformly along its length; easily mistaken for females of other sunbirds. The only features on the olive upperparts are indistinct paler eyebrows and lines running under the eyes, and yellow edging to the wings. Although often hidden, the male has yellow or whitish (not red) tufts at the shoulders. Singles are local and inconspicuous at the edges of lowland and riverine forest, sometimes entering secondary growth; it joins mixed-flocks and is frequently attracted to epiphytes in mossy clumps. Calls a high-pitched “tseeep” and trills. Little Green and Fraser’s sunbirds are similar to Bates’s but brighter, with straighter bills and more distinct yellowish eye-rings; Ursula’s Sunbird has a long decurved bill and grayish face and underparts.

Small, drab tyrannulet found in the lowlands from eastern Guatemala and Belize south to extreme northwestern Colombia. Fairly inconspicuous; usually found as singles or pairs in middle to upper levels of forests, plantations, and second-growth. Typically perches fairly horizontally with the tail held slightly cocked. Feeds mainly on berries. Note the dull whitish eyebrow, small bill, and bright yellow edging on wing feathers.
