Black-billed Flycatcher
Aphanotriccus audax
A fairly small flycatcher with a limited range in eastern Panama and northwest Colombia. Brownish-olive above with an olive chest and a yellow belly. Note two buffy wingbars on dark wings and a grayish face with indistinct whitish spectacles. Bill completely dark. Occurs in the understory of lowland forest. Distinctive song starts with two high-pitched notes that slur into a lower sputter.

Red-throated Thrush
Turdus ruficollis
This eastern counterpart of the Black-throated Thrush also breeds in montane areas and winters in lower-elevation areas on average. Males gray above and white below, with a brick-red throat and supercilium. Female paler, with more streaking on the breast and light suffusion of red on the face. Streaky and drab young birds can be difficult to distinguish from Black-throated; chestnut outer tail feathers and orange suffusion to the throat area indicate Red-throated. In areas of overlap, beware hybrids that may show features of both species. Pleasant song is simpler than that of Black-throated, and is composed of fluty whistles and trills. Calls include typical “chekchekchek” and high, thin “tseee.”

Olivaceous Thornbill
Chalcostigma olivaceum
Dark, short-billed hummingbird found at very high elevations in the Andes. Plumage is olive-green; adult male has a colorful “beard” that is reduced or lacking in females and immatures. It inhabits open grassland and areas with scattered shrubs above treeline. Unlike almost all other hummingbirds, it regularly lands on the ground to feed on tiny flowers protruding from the grass.

Northern Cardinal
Cardinalis cardinalis
Striking and familiar backyard bird throughout most of eastern North America; also occurs in the southwestern U.S. and fairly extensively in Mexico. Crest, large red bill, and long tail render this species distinctive even with a poor view. Male is entirely red with a black face. Female is brownish overall with redder wings and tail. Usually seen in pairs or small groups near dense cover, especially thickets near forest edges. Frequently visits bird feeders. Listen for high-pitched metallic chips and series of loud, sweet whistles.
