Source-derived summary

The grey warbler-finch (Certhidea fusca) is a species of bird, one of Darwin's finches in the tanager family Thraupidae. Sometimes classified in the family Emberizidae, more recent studies have shown it to belong in the tanager family.

It is endemic to the Galápagos Islands, Ecuador.

This species is closely related to the green warbler-finch, and were formerly considered conspecific, but both species differed in appearance, distribution, habitat, and song. The nominate subspecies is from Pinta and Marchena, becki from Darwin and Wolf, mentalis from Genovesa, bifasciata from Santa Fé, cinerascens from Española, luteola from San Cristóbal, and ridgwayi from Floreana. Grey warbler-finches are found mostly in the shrubland and dry forest of smaller drier islands, and have a suitable coloration for their habitat.

Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist montane forests, and subtropical or tropical dry shrubland.

Editorial summary

This brief starts where responsible research should: with the source description of “Grey warbler-finch” as species of bird. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—2011, 2010—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Grey, warbler-finch and species can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of bird. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Nov 28, 2025. The linked authority identifier is Q3109622. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2011 and 2010.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
