En: Mangrove Ecosystems: Biogeography, Genetic Diversity and Conservation Strategies (2013), p. 1-16Tema: Mangrove Finch Camarhynchusheliobates is endemic to the Galápagos Islands, Ecuador and today found only in north-west Isabela. The finch, one of the iconic Darwin’s finches (Geospizinae), has specialised to live in mangrove forest, a very rare habitat in the typically arid, volcanic, islands, and further specialised to live in mangrove separated from the sea but still inundated on high tides. The separation from the sea allows leaflitter to build up on the forest floor in mangroves with no crab species. Presumably naturally rare with such a restricted choice of habitat, Mangrove Finch is threated by a range of natural events and invasive animals especially Black Rat Rattusrattus and the parasitic fly Philornis downsi. Future conservation proposals are outlined.
