Zeledon's Antbird

This small warbler-like bird is unremarkable in appearance, but surely not the plainest of the white-eyes; look for a pale eye with a very narrow white eyering, grayish upperparts, and contrasting pale yellow throat. Endemic to the island of Yap, in the Western Caroline Islands of Micronesia, where it inhabits a wide range of forested and brushy habitats. The only other white-eye on the island, Yap White-eye, is dark olive-brown overall and has a much more prominent eyering. Forages actively in flocks. Gives high-pitched, scratchy trills and chirrups, comparable to parakeet and sparrow calls.

A delicate-looking inhabitant of densely vegetated wetlands, where it scrambles over floating plants and between the stems of standing ones. Brown above and pale gray below, with a small black mask around the eye bound in by two bold white stripes. Prefers to run away instead of fly; flight is weak, with dangling legs. Call is a loud, raspy “kii-kah,” often repeated.

Unique foliage-gleaner of dense bamboo in humid montane forest from low to mid elevations in the east slopes of the Andes. Despite its name, the bill is only very slightly recurved. Most easily found by its long, dry song. Generally in primary forest, far from human settlement, singly or in pairs. Tends to stay on small territories for long periods. From other foliage gleaners by rufous throat and supercilium, even streaking below, and straight culmen. Song a long series of accelerating but slightly sputtering dry “cak” notes.
