Lavender Waxbill

A small, brown bird of rainforest canopy. Note upturned mandible, white whisker mark, and pale streaking on underparts and back. Follows mixed-species flocks in the canopy but is rarely encountered. Bores into dead twigs and vines for insects, and may climb briefly on larger branches to probe bark crevices. Song is 4–6 high notes, dropping slightly in pitch at end; delivered forcefully but with a thin quality and thus easily overlooked. In central and western Amazonia, compare with very similar Streaked Xenops, from which it is best separated by Slender-billed’s slower song. Readily distinguished from Rufous-tailed Xenops by prominent white whisker streak.

Also known as Rock Shag, this rather small cormorant is fairly common along rocky coasts where it feeds mainly in inshore waters. Nests colonially on cliffs and other steep surfaces, sometimes on jetties with colonies of Imperial Cormorants. Adult is distinctive with a white body, black head and neck with variable white face patch, and a red eyering. All-dark juvenile told from Neotropic Cormorant by pink feet and dark face with reddish eyering.

A small dull-colored warbler with an indistinct pale eyebrow, a dull greenish upperside, a pale throat, and dull yellowish underparts. Usually shows an indistinct wingbar. Singles, pairs, and small groups inhabit lowland and hill forest, including secondary forest. Often joins mixed-species flocks. Sings a variable high-pitched warble mixed with twittering phrases. Easily identified as the only warbler in its limited range. Separated from other small yellowish birds such as flowerpeckers and sunbirds by the shape of the bill.
