The Genovesa ground finch (Geospiza acutirostris) is a small bird native to the Galápagos Islands. It was considered a subspecies of the sharp-beaked ground finch (Geospiza difficilis) endemic to Genovesa Island. The International Ornithologists' Union has split the species. Other taxonomic authorities still consider it conspecific.
In the whole-genome phylogeny of Lamichhaney et al. (2017), G. acutirostris is shown to be very far from G. difficilis. In fact, G. difficilis does not fall in the same part of the tree as other Geospiza. Wikipedia →

Rare
Under 5% of wildlife watchers report a Genovesa Ground-Finch sighting in Galápagos Islands on a given day, based on 516 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 65th most-seen of the 114 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Genovesa Ground-Finch in Galápagos Islands on a given day, against under 5% in September to May, the lowest months. Those are among Galápagos Islands's driest months, with almost no rain against 50 mm in March.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Genovesa Ground-Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Galápagos Islands, in our data
Galápagos Islands is the only park on Wallace's Line with enough records to rate Genovesa Ground-Finch sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Geospiza
The closest relatives of the Genovesa 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 Genovesa Ground-Finch is recorded against all the birds logged in Galápagos Islands (516 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.
