Medium tree finch

Species of bird

The medium tree finch is a critically endangered species of bird in the Darwin's finch group of the tanager family Thraupidae. It is endemic to the Galápagos Islands where it is only found on Floreana Island. Its name is derived from the fact that the bird's beak is intermediate in size between that of the small tree finch and the large tree finch. Because it has a very small range on a single island, and because of the introduction of a parasitic fly which kills the nestlings, the International Union for Conservation of Nature has rated the medium tree finch as "critically endangered".
