Family Tanagers (Thraupidae)

Least Concern

Sharp-beaked Ground-finch (Geospiza difficilis)


French: Géospize à bec pointu German: Spitzschnabel-Grundfink Spanish: Pinzón de Darwin picofino

Geospiza difficilis


, 1888,

Pinta (formerly Abington Island), Galapagos Islands


Relationship to other members of genus has always been troubled (hence the name difficilis). Previously considered conspecific with G. septentrionalis and G. acutirostris, but recent molecular work now confirms comments in HBW that both of those are more closely related to other members of Geospiza and must therefore each be treated as a separate species#R#R. Race debilirostris (Santiago) now considered synonymous with present species, as it is genetically nested between populations of Fernandina and Pinta#R. Monotypic.


Pinta, in N Galapagos Is, and Fernandina and Santiago, in W & C Galapagos Is. Previously recorded on Santa Cruz (last seen between 1932 and 1939), Floreana and San Cristóbal#R.
