One of the smallest finches. Sister species of the Gray Warbler Finch (Certhidea fusca) (Lamichhaney et al., 2015). Brownish-olive back, olive-white ventral, darkish remiges and rectrices with greenish or brownish edges, olive-colored head with no contrasts, lighter lore and periorbital areas, mostly uniform. Some males have an orange bib. Darkish or pinkish-orange legs. Locally abundant, easy to detect by its vocalization. It has no distribution overlap with the Gray Warbler Finch, so its identification is very easy, both by vocalization (which differs greatly from the other finches it shares its habitat with) and by morphology, as it is the only finch with such a thin bill in its habitat. It prefers highland or transitional areas, especially Scalesia sp. forests. Sometimes confused with the Mangrove Warbler (Setophaga petechia), although the latter is larger, has a contrasting ventral with a whitish throat, greenish flanks and undertail, gray neck sides, a very marked whitish periorbital, a longer bill, and a different vocalization. Monotypic.

Geographic Distribution: Fernandina, Isabela, Santiago, Pinzón, Rábida, Santa Cruz, and Baltra (BirdLife International, 2023).
