Silvery-fronted Tapaculo
Scytalopus argentifrons
Tapaculos are small, plump, short-tailed, mostly gray birds that are as sneaky as mice. Silvery-fronted is the only tapaculo in its range, and the male has a distinctive whitish eyebrow. Also look for browner flanks with dark bars. Females don’t have the white eyebrow but are still distinctive in range because of the overall dark color and extremely furtive habits. Rarely seen well; stays on or near the ground in the forest understory. Listen for the song: a series of chips starting off fast, gradually getting slower and louder.
Identification
The silvery-fronted tapaculo is 11 cm (4.3 in) long and weighs 17 g (0.60 oz). The male of the nominate subspecies is mostly sooty black; the lower breast and belly are paler. The flanks and crissum (the area around the cloaca) are brownish red. It has a silvery forehead (the "front") and a white supercilium. The male Chiriqui is darker with a less prominent supercilium. The females of both subspecies do not have a supercilium; their upper parts are dark brown, the throat and breast are dark gray, the belly blackish, and the flanks and crissum brighter brownish red than the male's. The juvenile is similar to the female but darker with brown "scales" on the underparts.
Taxonomy
The silvery-fronted tapaculo has two subspecies, the nominate "silvery-fronted" Scytalopus argentifrons argentifrons and the "Chiriqui" S. a. chiriquensis. The Chiriqui subspecies has at times been considered a separate species.

Range and habitat
The silvery-fronted tapaculo is the only member of its family whose entire range is in Central America. (The Tacarcuna tapaculo, S. panamensis, is found in far southern Panama and Colombia.) It inhabits the Talamancan montane forests at elevations of 1,000 to 3,000 m (3,300 to 9,800 ft). The Chiriqui subspecies is found only in western Panama. The nominate S. a. argentifrons has the wider range, from western Panama north through Costa Rica almost to the border with Nicaragua. If frequents thickets and bamboo in the undergrowth of humid primary forest and secondary forest, especially in ravines and along streams.

Pacific Parrotlet
Forpus coelestis
Tiny, sparrow-sized parrot of lowlands and foothills in western Ecuador, western Peru, and far southwestern Colombia. Most common in dry habitats such as desert and deciduous forest, but has spread into humid areas in response to deforestation. Green with blue patch behind eye; male also has blue in wings and on rump, but these features can be hidden by folded wings. Typically found in small flocks that give high-pitched, metallic chirps and chatters.
Tristram's Warbler
Curruca deserticola
Small, long-tailed Curruca warbler, very similar to Spectacled and Subalpine Warblers. Males are distinctive with very deep rusty underparts, a rusty throat (sometimes paler mid-throat), rusty wings, and a hint of pale buff moustache. Females are pale brown and less distinctive with normally rather warm-toned underparts. Breeds on mountain slopes covered in dense, low bushes, tamarisk scrub, and vegetated desert wadis; non-breeding habitat is sometimes lower in elevation, but typically similarly open and scrubby. Song a scratchy whistle. Call a low "trrrrr."
Gray-breasted Spurfowl
Pternistis rufopictus
A large gray-and-brown francolin with bare red skin on the throat and around the eyes. Also note the red bill, the dark gray legs, and the chestnut, buff, and black markings along the sides of the belly. Pale patches in the outer wings are conspicuous in flight. Found in fairly dry thorn savanna, woodland, and thickets, usually in pairs or small groups. Similar to Red-necked Francolin, but there is little overlap in range, and separated by the brown legs and many plumage details. Also similar to Yellow-necked Francolin, but easily separated by the red or sometimes orange (rather than yellow) throat. The call is a fading series of grating “kreaaak” notes.
