The Medium Tree Finch or Camarhynchus pauper is a critically endangered species of bird in the Darwin’s finch group of the tanager family Thraupidae. It is endemic to the Galapagos Islands. This species is only found on Floreana Island at elevations above 250 m in moist highland forest habitat. Prime breeding habitat is dominated by Scalesia pedunculata trees.
The medium tree finch or Camarhynchus pauper is threatened by introduced predators such as rats, mice, cats and the smooth-billed ani, as well as habitat loss, which has occurred through clearance for agriculture. The introduced fly Philornis downsi is a significant threat to the survival of medium tree finch or Camarhynchus pauper. Parasitic larvae of this fly live in the nest material and feed on the blood and body tissues of nestlings. P. downsi causes high nestling mortality in the medium tree finch.
The diurnal Galapagos short-eared owl is its only remaining natural predator. Medium tree finches or Camarhynchus pauper generally lay two to three eggs. Eggs are incubated for approximately 12 days, and nestlings are fed by both parents at the nest for approximately 14 days before becoming fledglings.
The range of beak sizes of the medium tree finch on Floreana and the large tree finch, Camarhynchus psittacula, on Isabela is roughly the same. This reflects the fact that the two species feed on the same type and size of insect. The beak of the medium tree finch or Camarhynchus pauper is intermediate in size between the small tree finch and large tree finch. All three species are found in the same habitat country and area.
