Camarhynchus heliobates

The mangrove finch (Camarhynchus heliobates ) is a species of bird in the Darwin's finch group of the tanager family Thraupidae. It is endemic to the Galápagos Islands. It was found on the islands of Fernandina and Isabela, but recent surveys have failed to record the species on Fernandina. It has been classified as critically endangered by BirdLife International, with an estimated population of between 60 and 140 located in two large mangroves on Isabela. A study has shown that the two small populations remaining on Isabela Island have begun undergoing speciation and that one or both populations will eventually become extinct due to a lack of interbreeding.



Biogeographical realms

As its name suggests, the mangrove finch lives in the mangroves of the Galápagos Islands. The mangrove finch feeds upon the various insects, larvae, spiders, and vegetable matter found in the mangroves. It closely resembles the far commoner woodpecker finch, but is not known to use tools.

In January 2014, project researchers reported successfully raising 15 mangrove finch chicks in captivity and releasing them back into the wild. Since then, 36 fledglings have been "head-started" and the project is building on this success.

The Mangrove Finch Project is a bi-institutional project carried out by the Charles Darwin Foundation and Galapagos National Park in collaboration with San Diego Zoo Global and Durrell Wildlife Conservation Trust. The project is supported by the Galapagos Conservation Trust, the Mohamed bin Zayed Species Conservation Fund, Durrell Wildlife Conservation Trust, The Leona M. and Harry B. Helmsley Charitable Trust, Galapagos Conservancy, and the British Embassy in Ecuador.
