Three-striped Warbler
Basileuterus tristriatus
Active, often noisy warbler found at lower to middle levels of montane cloud forest. Note the olive upperparts and dark and pale pattern on head. Underpart color and extent of cheek patch vary through its range. Dark stripes on head usually contrast with back, and eyebrow is white, not yellow – these two features help to separate it from other similar warblers in range. Usually seen in pairs or family groups. Typical song begins as a rising trill and then morphs into chaotic chattering.

The three-striped warbler measures 13 cm (5.1 in) in length. It is mostly olive-brown with a buffy belly and underparts. It has distinct black and white striping on the head and a dark cheek. Male and female three-striped warblers have similar plumages.<p>Their song is a rapid series of squeaky chirps.

White-tailed Alethe
Alethe diademata
A forest skulker with clean-cut pale underparts, a gray wash on the side of the breast and face, and rusty brown upperparts and central crown. The tail has distinctive white tips to the outer feathers. Juvenile is heavily spotted above. A shy and inconspicuous resident in the dense understory of lowland and mid-altitude forest up to 1500 meters, found singly and in pairs; several individuals may follow ant swarms, where they lose their fear of humans. Sings a loud musical 3–4 note “whooo-wheet-whooee” and similar melodic notes; also gives harsh “chht” calls.
Rufous-capped Babbler
Cyanoderma ruficeps
Medium-sized songbird, dark olive above, dusky yellowish below, with a yellow face and rufous crown. Moves about low in dense bushy vegetation or bamboo in pairs or flocks, often with other species. Song, a series of clear, descending, bell-like whistles, easily imitated; chatters nasally when alarmed.
Masked Gnatcatcher
Polioptila dumicola
Bold patterned gnatcatcher usually found in the canopy of savanna, open woodlands, and forest edges where it may join mixed-species flocks. Largely grayish overall with a white-edged black tail. Males have a black mask while females have a small black ear patch on a generally pale face. Males of the subspecies from Northwest Brazil are whiter below and grayish in other populations.
