Warbler finch  (Certhidea olivacea)

The most widespread of all Darwin’s finches, the warbler finch is found on every major island in the Galapagos. The green warbler finch mainly occupies larger, inner islands of the archipelago, while the grey warbler finch inhabits the smaller, outer islands (6).

The green warbler finch is only found in the Scalesia Zone, a lush, humid evergreen forest dominated by the daisy tree (Scalesia pedunculata), which occurs between elevations of 300 and 700 metres (5) (6). In contrast, the grey warbler finch inhabits the arid zone, where the vegetation comprises scattered deciduous trees, shrubs and cacti (5).
