The sharp-beaked ground finch (Geospiza difficilis) is a species of bird in the Darwin's finch group of the tanager family Thraupidae, and it is native to the Galápagos Islands. It has a mass of around 20 grams (0.71 oz) and the males have black plumage, while females have streaked grey plumage. This finch was described by Richard Bowdler Sharpe in 1888.
This relatively small, slender-billed finch is found on Fernandina, Santiago, Pinta, formerly Santa Cruz and Floreana. It breeds in the humid highlands and disperses afterwards. It is possible it still occurs on Isabela.
Both the vampire ground finch and the Genovesa ground finch were considered subspecies. The International Ornithologists' Union have split them based on strong genetic, morphological, and song evidence, while other taxonomic authorities still consider them conspecific. Wikipedia →

Rare
Under 5% of wildlife watchers report a Sharp-beaked Ground-Finch sighting in Galápagos Islands on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 96th most-seen of the 114 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sharp-beaked Ground-Finch in Galápagos Islands on a given day, so our monthly data shows no clear season.
Only Galápagos Islands, in our data
Galápagos Islands is the only park on Wallace's Line with enough records to rate Sharp-beaked Ground-Finch sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Geospiza
The closest relatives of the Sharp-beaked Ground-Finch that you can see in Galápagos Islands (genus Geospiza, Ground-Finches and Cactus-Finches) are Small Ground-Finch (about 70%), Medium Ground-Finch (about 50%) and Common Cactus-Finch (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sharp-beaked Ground-Finch is recorded against all the birds logged in Galápagos Islands (19 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
