One of the 4 finches on WAnimals

Birds · Passeriformes · Thraupidae

Cocos Finch

Pinaroloxias inornata

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The Cocos finch is the only one of Darwin's finches that does not live in the Galápagos: it belongs to the same group as those, but it colonised an island more than 700 kilometres away. Its history is the reverse of its relatives': instead of diversifying into several species with different bills, it stayed as a single one that does everything.

8 years

Diet

Omnivore

Combines animal and plant food depending on availability.

Activity

Diurnal

Social structure

In pairs

Usually lives in pairs, sometimes for life.

Sighting difficulty

Moderate

Fun facts

  • It is the only one of Darwin's finches outside the Galápagos, and its history is the reverse of its relatives': where they split into more than a dozen specialised species, it remained a single one that exploits every resource.
  • Each individual develops its own feeding technique and keeps it for life: some probe bark, others look for nectar, others catch insects in flight, and that individual specialisation takes the place of speciation.
  • That phenomenon, individual specialisation within a single species, is studied as an alternative to adaptive radiation and has made this finch a celebrated case in evolutionary ecology.
