Zeledon's Antbird

Tiny flycatcher, more often heard than seen. In addition to tiny size, note elongated crown feathers (usually held flat) and plain underparts. Found in a variety of forest types, especially those on sandy soils. May be alone or in pairs; perches well inside dense vegetation, usually at lower levels but occasionally into subcanopy. Sits still and darts upward to foliage for insect prey. Song is a hard, buzzing trill, repeated over and over and with little geographic variation. Similar to Helmeted Pygmy-Tyrant and often found in the same habitat; best told by voice, and, if seen well, by clear pale underparts that lack olive mottling.

A relatively small and inconspicuous mountain-tanager found in the upper subtropical and temperate zones of the Andes. Blue above with a yellow belly and black head. Buffy breast band is not super conspicuous. Look for unique spangled blue eyebrow. Sexes alike. Found alone or in pairs, typically moving quietly through the understory of forest and edge. Often follows mixed-species flocks.

Large red-headed woodpecker, widespread from Panama to Paraguay. Found in lowland forest and edges, often perched conspicuously high up on a snag or large tree. More apt to be seen in open habitats compared with Red-necked Woodpecker, but significant overlap. Male is distinctive with barred underparts and almost entirely red head with a black-and-white patch on the cheek. Female distinguished from other large woodpeckers (such as Lineated) by very broad white stripe on face and white V on back. Listen for loud knocking drum as well as various chattering noises.
