They are sexually dimorphic in that the males have black feathers from the tail, breast, nape, and crown. Unlike male finches found in Galapagos island, male Cocos finches have black beaks year-round. Female Cocos finch have a lighter brown complexion compared to a male Cocos finch. There is a black splattering of feathers on their breast area down to the flank and rump. The belly of the female Cocos finch is milky white compared to the mantle of the bird. The nape and crown area are more noticeably black. The call of a Cocos finch can be described as a "buzzy" like sound with a high-pitched ending note. The beginning of the call can form a “djirr” sound followed by a high pitched “tiew” sound. Calls can also include a high pitched “phzzzz” sound.

Distribution Area
The Cocos finch is exclusively found in Cocos Island (1,997 km area), 580 km SE from 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 km within the island. The habitat of the Cocos finch is mostly within Hibiscus thickets, closed-canopy forest and woodland forest. The climate within Cocos Island is described to be a typical rain forest climate with high humidity and chances for rainfall. The island has a varied landscape with bodies of lakes, streams, and caves and is home to other species including endemic lizards (only 2 species), small mice, small cats, and some migratory birds.

Species Status
Cocos Island is a natural reserved island and that there is limited human interaction towards the Cocos finch and to other Cocos Island inhabitants. While there has been increasing tourism around the island, there is no evidence of high disturbance rates from these tourists to affect the wildlife in the island including the Cocos Finch. While the predation and disturbance rate of Cocos finch are low along with a steady population rate, the IUCN deems the Cocos finch to be vulnerable due to the small habitat it occupies; about 30 km of the whole Cocos Island. As of now, there are about 6,000-15,000 Cocos Finches living isolated in Cocos Island.
