This is a variation from the other finches because some of them have jet-black plumage, or bright orange beaks, but this bird has completely dull colors. It also occurs in closed-canopy forest and in disturbed vegetation. Darwin's finches are a classic example of species diversification by natural selection. Some different groups of them include Grosbeaks, Rose Finches, Canaries, Green Finches, Gold Finches, and more. The variation in foraging behaviors are hypothesized to be possible by observational learning from other Cocos finches. This species is endemic to Cocos Island, S of Costa Rica.  Cocos finches are not known to have traveled outside of Cocos Island making its habitat and reproduction range to only be at 30 km2 within the island. The Cocos Finch is common to abundant throughout its restricted range.

This means that plumage is not the easiest way of identifying the finches. In all, 14 species are now recognized, 13 from the Galapagos and one from far-distant Cocos Island. The Cocos Finch feeds on arthropods, nectar, soft fruits, grass seeds and small lizards. The song is often preceded by a metallic note, and rises at the end. PROTECTION / THREATS / STATUS: The female is brownish. Daphne Major had a long drought which affected the food sources. Deer (native), pigs and goats (introduced) degrade the natural habitats. We performed a comparative analysis of expression patterns of various growth factors in species comprising the genus Geospiza. The tail is brown with cinnamon tips, and occasionally feathers centres too. The population is suspected to be stable.

INTRODUCTION: All: Kokosinselammer The Cocos Finch is found on Cocos Island, S of Costa Rica. This bird is the only Darwin’s Finch on Cocos Island, S of Costa Rica. Darwin’s finches are characterised by a wide spectrum of beak forms, with the slender, pointed beak of the Cocos finch being particularly distinct (2) (5) (6). Similar to the other Darwin Finches, the male Cocos Finch is pure black, and the female is a blackish-brown with olive streaks. Third, the molecular data corroborate the placement of the warbler finch at the base of the Darwin’s finch tree as suggested by some taxonomists ( 3 ) and by the allozyme frequency data ( 5 ). They grow around 12 cm and weigh around 16 grams. 10.2305/iucn.uk.2016-3.rlts.t22723792a94833441.en, "Birds, Mammals, & Reptiles of the Galápagos Islands: An Identification Guide.

The pointed beak of the Cocos Finch distincts them from the other Darwin Finches. But currently, none of these potential threats appear to affect the numbers (6,000/15,000 mature individuals). Darwin’s finches vary in shades and tones, but not enough to make the changes in appearance as obvious as other species of birds. Several hundred different species of these birds live across the globe. The Cocos Finch is found on Cocos Island, S of Costa Rica. The ground finches with the larger beaks in figure 14.9 feed on seeds that they crush in their beaks, whereas those with narrower beaks eat insects, including the warbler finch … The Cocos Island Finch is a larger species of hummingbird, weighing 12.5 grams and is 12 cm long.
