The green warbler-finch (Certhidea olivacea) is a species of bird, one of Darwin's finches (which are mainly found in the Galápagos Islands) in the tanager family Thraupidae. Sometimes classified in the family Emberizidae, more recent studies have shown it to belong in the tanager family.
When Darwin collected it in 1835 during the Beagle survey expedition he mistakenly thought it was a wren, but on return to England he was informed in March 1837 by the ornithologist John Gould that the bird was in the group of finches.
It is endemic to the Galápagos Islands, Ecuador. This species is closely related to the grey warbler-finch, and the two were formerly considered conspecific, but both species differ in appearance, distribution, habitat, and song. Holding a distinctive place in the evolutionary history of Galápagos finches, phylogenetic studies suggest that the warbler-finches represent one of the earliest branches in the radiation of Galápagos finches, diverging prior to the more well-known ground finches and tree finches. With its slender, pointed beak adapted for capturing insects, the green warbler-finch occupies a unique ecological niche within the Galápagos archipelago. As such, the green warbler-finch serves as a crucial species for understanding the evolutionary processes that have shaped the remarkable avian diversity found in this iconic ecosystem. Wikipedia →

With luck
About 10% of wildlife watchers report a Green Warbler-Finch sighting in Galápagos Islands on a given day, based on 1,332 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 43rd most-seen of the 114 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January and October
In those months about 20% of wildlife watchers report a Green Warbler-Finch in Galápagos Islands on a given day, against about 10% in February–September and November–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Green Warbler-Finch sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Galápagos Islands, in our data
Galápagos Islands is the only park on Wallace's Line with enough records to rate Green Warbler-Finch sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Green Warbler-Finch is recorded against all the birds logged in Galápagos Islands (1,332 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
