Pied Bronze-Cuckoo

Dull, relatively unmarked olive-brown warbler with a prominent yellowish-white eyestripe, faint wingbars, and pale whitish underparts. Visually inseparable from Japanese and Kamchatka Leaf Warblers; listen for song, an electric chattery trill. Also gives a metallic two-noted call and a short harsh buzz. Breeds in shrubby areas, often near water, throughout the Eurasian taiga. Breeding range extends to Alaska, where it is the only leaf warbler. Winters in lowland and foothill forest, forest edge, and gardens, primarily in Southeast Asia.

Small, short-billed, warbler-like sunbird. The distinctive male has a blue bib. The female is drab but can be identified by its small pale eyebrow, greenish back, and overall size and shape. Found in forest at low elevation, mostly close to the coast. Often in forest understory; less conspicuous than a typical sunbird. Most distinctive vocalization is a rapidly repeated “tchew”. Shape, size, and olive-green back separate Plain-backed from other sunbirds.

Scarce cotinga restricted to dry lowland forest in northwestern Peru. Male is gray with a reddish belly and forehead and white wingbars. Female is gray and buff with strong black streaking. Both sexes have a shaggy crest and a yellow eye. Found in areas with abundant mesquite and acacia trees, where it feeds mainly on leaves, buds, and other plant parts. It is usually first detected by its weird, buzzy calls that sound a lot like a kazoo.
