This species previously included as subspecies the Genovesa Ground Finch (Geospiza acutirostris) and the Vampire Finch (Geospiza septentrionalis), so in literature prior to 2015, its geographic distribution across islands was much wider than it is currently known. It inhabits the highlands of the islands (Kleindorfer et al., 2022). It is very similar to the Small Ground Finch (Geospiza fuliginosa), with which it shares its geographic distribution, but the beak of the Sharp-beaked Ground Finch is a bit longer, thinner at the tip, and the culmen is straight, not curved. It is also similar to the Vampire Finch and the Genovesa Ground Finch, but they inhabit different islands. Monotypic.

Geographic Distribution: Fernandina, Pinta, and Santiago, extinct in Santa Cruz, Floreana (BirdLife International, 2023), and San Cristóbal (Fessl et al., 2017).

Description extracted from: La Grotteria (2023).
