The Genovesa ground finch is a small bird native to the Galápagos Islands. It was considered a subspecies of the sharp-beaked ground finch endemic to Genovesa Island. The International Ornithologists' Union has split the species. Other taxonomic authorities still consider it conspecific.
Region
Galápagos Islands
Typical Environment
Restricted to Genovesa, an arid low island dominated by coastal scrub, lava fields, and Opuntia cactus zones. It forages on open ground, along rocky shores, and within low shrubs. The species uses sparsely vegetated habitats where seeds and arthropods are abundant, and it may exploit seasonal blooms and cactus resources. Nesting typically occurs in shrubs or low trees in the arid zone.

One of Darwin’s finches, the Genovesa ground finch is a showcase of adaptive radiation in the Galápagos, with a notably sharp, pointed bill for taking small seeds and insects. It was long treated as part of the sharp-beaked ground finch complex but is now recognized as a distinct species by the IOC. Its small, isolated population on Genovesa makes it vulnerable to island-specific threats such as invasive parasites and habitat changes.
Temperament
social and active
Flight Pattern
short rapid wingbeats with low, direct flights
Social Behavior
Often seen in small groups outside the breeding season, foraging on the ground and in low shrubs. Breeding is typically monogamous, with cup nests placed in shrubs or low trees. Pairs defend small territories during nesting but tolerate neighbors at feeding sites.
Migratory Pattern
Resident
Song Description
The song is a simple, rapid series of thin trills and buzzes delivered from exposed perches. Calls are sharp, metallic chips used to keep contact within small groups.
Plumage
Males are largely uniform sooty-black with a matte finish; females and immatures are brown with heavy streaking on the underparts and back.
Diet
Consumes small seeds, plant material, and a variety of arthropods such as beetles and caterpillars. It will vary its diet with seasonal availability, taking more insects during breeding. Cactus seeds and flowers may be used when available, and it opportunistically gleans from ground litter and low foliage.
Preferred Environment
Feeds on open ground, among lava rocks, and within arid scrub and cactus stands. Often forages in mixed finch groups where resources are patchy.
