Floreana Mockingbird

Mimus trifasciatus

The Floreana Mockingbird, Mimus trifasciatus, is classified as Critically Endangered on the IUCN Red List of Threatened Species™. It survives today only on two tiny islets off the coast of Floreana Island in the Galápagos.  Current population estimates are 47 birds on the 9ha Champion Island and 400-500 on the 80ha Gardner-por-Floreana.

The Floreana mockingbird has a special place in science because it inspired Charles Darwin, during the HMS Beagle voyage, to develop the Theory of Natural Selection. In 1835, Darwin recorded the mockingbird as being common on Floreana but it must have declined rapidly as the last reported sighting here was in 1868.  Human hunting, predation by invasive mammals and disappearance of the prickly pear cactus, a favoured place to nest and a source of food, are thought responsible.  

A new effort to restore Floreana back to its former glory has been launched by the Galápagos National Park, aiming to remove other species intrusion from the main island and re-introduce marooned endemic species, including the Floreana Mockingbird.
