Typical antpitta with long legs and short tail. Inhabits Andean cloud forest in Colombia, eastern Ecuador, and extreme northern Peru.

Delicate Prinia
Prinia lepida
Tiny, disproportionately long-tailed, active, and vocal. The upperparts are gray-brown with heavy dark streaking, the underparts are pale, and each tail feather shows both pale and dark tips. Generally found in rather moist habitats within arid zones, including field margins, riparian woodland, scrub, gardens, and wetlands; can be quite numerous. Very vocal, especially in spring. The song is a rattling series of dry chirps, subtly different from the slower-paced song of Graceful Prinia. Males often sing from obvious perches. Visually extremely similar to Graceful Prinia, but there is little overlap in range. In any areas of overlap, best separated by song, but Delicate is also slightly longer- and narrower-tailed and browner.

Saipan Reed Warbler
Acrocephalus hiwae
A relatively large plain brown reed warbler with a pale throat, a yellowish face, a darker cap and tail, and an absurdly long decurved bill. Found in areas of tall dense grasses, reed marshes, and scrubby thickets up to 400 meters of elevation. Song is a slow, loud reel of whistles, warbles, harsh “chak” notes, and trills. Call is a loud, offensive “tchak.” Often sings at night.

Pacific Reef-Heron
Egretta sacra
A small heron that hugs rocky coastlines. Light-morph individuals are usually white all over, though some may show patches of gray. Dark-morph individuals are entirely dark gray. Both morphs have a yellowish green bill and legs. Light morph adults are distinguished from egrets in the area by their distinct short-legged appearance and noticeably thicker bill.
