The Warbler Finch is common and widespread in the Galapagos. This finch is found in all vegetation zones, and most numerous in the humid zones.
The Warbler Finch is the smallest of Darwin’s finches, with the smallest, narrowest bill. The color of the plumage ranges from pale - grey to olive - green, and the underparts range from white to buff. Male and female Warbler finches generally have the same color, although some adult males develop an orange throat patch.
