Very similar to Vampire Ground-finch G. septentrionalis of Darwin and Wold, and Genovesa Ground-finch G. acutirostris. Similar to the Small Ground-finch with slightly longer and more pointed beak, with its upper edge almost straight.

Threats Affected by the parasitic fly Philornis downsi that causes heavy chick mortality, though data is missing.










Taxon category: Accepted

Syn.: Geospiza difficilis debilirostris Ridgway, 1894; Geospiza difficilis difficilis Sharpe, 1888; Geospiza difficilis septentrionalis Rothschild & Hartert, 1899; Geospiza nebulosa (Gould, 1837).

Taxon origin: Endemic


Least concern


Feeding type: Insectivorous


Feeding preferences: Feeds mainly on insects and arthropods, also snails in the more humid zones.

Trophic role: Carnivorous

Reproduction mode: Exclusively sexual

Reproductive biology: Male displays in front of a dome shape nest. Only females incubate (three to five eggs), both feed the chicks.


Map of specimen collection localities or observation records for this species in our collections database.

Distribution: Present in the highlands of Santiago, Fernandina and Pinta, where the Small Ground Finch occupies the drier zones. In the present, in Darwin, Wolf is other species (G. septentrionalis), and in Genovesa (G. acutirostris). It is now extinct on Santa Cruz.
