Zosterops brunneus

In the field, appears overall chocolate-brown with a slightly long blue-gray bill and blue-gray legs. Plumage is paler on the flanks and vent and darker near the face.

Warbling Doradito

Warbling Doradito

Pseudocolopteryx flaviventris

Small two-toned flycatcher, olive-brown above and yellow below. Note the rufescent crown patch. Found in tall-grass marshes, especially those with sedges. Typically difficult to locate, but during migration can be found in various areas with tall grass. The call is a series of nasal squeaky notes: “chek, chek, chek, chek-chick-chick-chiquetik.” The rather similar Dinelli's Doradito has a more olive-colored, less brownish back.

Niceforo's Wren

Niceforo's Wren

Thryophilus nicefori

Endangered songbird restricted to the western slopes of the northern part of Colombia’s eastern Andes. Note the white spectacles, striped face, and barred wings and tail. Very similar to the widespread Rufous-and-white Wren, but duller brown, lacking rich chestnut tones in the plumage, and its song tends to be faster and higher in pitch. Range is also helpful for ID, since the two species have limited, if any, overlap. Skulks in the understory of dry to semi-humid forest as well as in shady coffee and cacao plantations.

Chinese Blue Flycatcher

Chinese Blue Flycatcher

Cyornis glaucicomans

One of a number of confusingly similar blue flycatchers. Male is brilliant blue above with orange throat and breast; note off-white lower belly. His dark orange throat distinguishes him from Blue-throated Blue Flycatcher. Female is drab brown with an orange chest, white belly, and dull rufous tail. Note weak orangish eyering, dull tannish throat, and overall warm brown coloration. Brown flanks in both sexes. Breeds in montane and hilly forest, typically in areas with dense undergrowth; winters at lower altitudes. Musical song is composed of trills and whistles; calls are a hard “tak” or “chek.”
