Small Ground Finch or Geospiza fuliginosa is a species of bird in the tanager family Thraupidae. Endemic to the Galápagos Islands, it is common and widespread in shrub land, woodland, and other habitats on most islands in the archipelago.
Small Ground Finch or Geospiza fuliginosa commonly feeds on small seeds and parasites from the skins of Galápagos tortoises, and Galápagos land and marine iguanas. Collected in February 1967.
The small ground finch or Geospiza fuliginosa is the smallest of the ground finches, measuring 4.3 inches in length. Its beak is short and pointed, with a slightly curved culmen.
On average, the Small Ground Finch or Geospiza fuliginosa beak is smaller than that of the medium ground finch, but there is a significant overlap in size between the two, particularly on islands where only one of the two species exists. On islands where the two species compete directly, the difference between their beaks are greater.
The male Geospiza fuliginosa is black with white-tipped under-tail coverts, while the female and young are brown with streaked underparts.
There are observable phenotypic differences between finches that live in lowlands and ones that live in highlands, and this change is most likely attributed to adaptation. The finches seen in highlands have larger, more pointed beaks and smaller feet and claws compared to the lowland variety.
The small ground finch or Geospiza fuliginosa is an omnivore with a preference for vegetable matter. It feeds primarily on the ground or in low vegetation, eating seeds, buds, flowers, leaves and the occasional insect.
It forms symbiotic relationships with Galápagos tortoises and both marine and Galápagos land iguanas by gleaning parasites from their skins.
