Buff-rumped Warbler
Myiothlypis fulvicauda
Small ground-dwelling warbler frequently found around water, especially forested streams. Also often seen hopping along trails and sometimes around army ant swarms. Sexes alike; brown above and paler buffy-gray below with pale eyebrow. Frequently flicks tail back and forth so buffy rump and base of tail are very conspicuous. Listen for exceptionally loud song: a series of accelerating chips that increase in volume.

Rio de Janeiro Antbird
Cercomacra brasiliana
Medium-sized gray antbird with a long tail. An inhabitant of the understory of dense humid forest. Males are gray with a white patch on the back that is usually concealed. Females are rufous-brown overall. Both sexes have white spots on the wing coverts and white-tipped undertail feathers.

Jungle Owlet
Glaucidium radiatum
Squat little owl with dense barring all over the body. Lacks the false eyes on the back of the head possessed by many other owlets. Gives bursts of loud hollow trills, comparable to barbets, as well as a mellow “kaaaooo-kaaaaooo-kah-ow!” A forest species, found in densely wooded areas in lowlands and foothills. Most active at dawn and dusk.

Fire-crested Alethe
Alethe castanea
A common understory bird found in the undergrowth or on the ground in forests of all types, from the lowlands into the foothills. The reddish-brown back and tail are noticeable when the bird flies away in the undergrowth, but look also for the white undersides, dark gray legs, and gray face. This alethe’s fiery crest is hard to see in the field and often appears as a reddish-brown crown stripe. Sometimes imitates other species, including illadopsises. Distinguished from Brown-chested Alethe by its plain gray face, dark legs, and reddish crown stripe. Gives a distinctive two-parted whistle, “go where?”, with a distinct pause between the notes.
