The grey warbler-finch 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.
Region
Galápagos Islands
Typical Environment
Occurs on several of the drier, northern and central Galápagos islands where arid scrub and open shrubland dominate. It favors coastal and lowland zones with sparse shrubs, Opuntia cactus, and seasonally dry woodland. The species forages from the ground to the mid-canopy, often along ecotones between lava flows and scrub. It generally avoids the lush, humid highlands that are occupied by its close relative, the green warbler-finch.

One of Darwin’s finches, the grey warbler-finch has a slender, warbler-like bill adapted for picking small arthropods from leaves and twigs. It is confined to the drier islands of the Galápagos and shows subtle variation among island populations. Breeding is closely tied to seasonal rains, and like many Galápagos birds it can be affected by invasive species and the parasitic fly Philornis downsi.

Social Behavior
Typically seen singly, in pairs, or small loose groups while foraging. Pairs form during the wet season and build small cup nests concealed in shrubs. Both parents participate in feeding nestlings, and territory defense is most pronounced during breeding.

Resident
Song Description
A high, thin, warbler-like series of trills and tinkling notes delivered from low perches. Calls are soft, high-pitched tseep or tsit notes used to keep contact while foraging.
