The C. pauper or 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.
Their bill is moderately curved on both upper and lower edges, and slightly longer than it is deep. Males veha a black hood, brownish-olive upperparts, and a pale belly. The female is tan with whitish underparts. Both sexes have faint streaking on the breast.
The bill is black on breeding male and orange on females and non-breeding males. Large Tree-Finch has larger and more bulbous bill. Small Tree-Finch has slightly smaller bill and body.
Identification is much easier when more than one species is present to allow direct comparison. Medium Tree-Finch inhabits forest mainly in the highlands but is occasionally seen closer to the coast, where it may be only a seasonal visitor.
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.
