No other tanager has such a spangled appearance. Sexes alike. A fairly common member of mixed flocks from around 1,500–2,500 m, within forest and also at edges or in second growth.

Purple-tailed Imperial-Pigeon
Ducula rufigaster
A fairly large pigeon of lowland and foothill rainforest interior. Pale pinkish head, orange underparts, metallic emerald green wings and back, and a purple rump. It is usually solitary, difficult to see and does not usually fly above the canopy. Similar to Rufescent Imperial Pigeon, but Purple-tailed is found at lower elevations and has an obvious pale gray tail band. Call, two introductory “tuk-tuk” notes followed by a long, rather out of tune, rising then falling “ooo-woo-ooo”

Rodrigues Warbler
Acrocephalus rodericanus
A medium-sized yellowish-olive bird with a long tail that is often flipped up and down. Endemic to the remote island of Rodrigues. Found in secondary forest, scrub, and plantations. Feeds both in the undergrowth and up into the canopy. The cheerful song is a quick series of several musical warbling notes in an up-and-down pattern. The calls include “chek” notes and rattling scolds. There are no other warblers or otherwise similar species on Rodrigues, so identification is simple.

Happy Wren
Pheugopedius felix
Small, often very skulking wren of lowlands and foothills in West Mexico; endemic. Favors tropical forests, thorn forests, and thickets, usually with vine tangles. Heard more often than seen. Song a happy-sounding, repeated series of sweet whistles. Calls include a rising trill, like running your thumbnail along a comb. Plumage distinctive, with striped face bordered below by black whisker, and orangish underparts. Often occurs alongside and sometimes in the same bush as the much plainer and different-sounding Sinaloa Wren.
