The medium tree finch (Camarhynchus pauper) is a species of Darwin's finch. It is endemic to the Galápagos Islands, where it occurs only on Floreana Island. Its name derives from its intermediate size between the small tree finch and large tree finch. Due to its limited geographic range and its high breeding mortality following the introduction of the parasitic avian vampire fly, the medium tree finch is listed as critically endangered on the IUCN Red List.
This species is only found on Floreana Island at elevations above 250 meters (820 ft) in moist highland forest habitats, across an range of about 24 km². Prime breeding habitat is dominated by Scalesia pedunculata trees, although the species also occurs in the surrounding agricultural zones. A 2008 survey estimated the number of medium tree finches as 1,620, while a series of surveys between 2014 and 2016 put the number of medium tree finch territories at between 3900 and 4700.
The diurnal Galapagos short-eared owl is its only remaining natural predator. Medium tree finches generally lay two to three eggs. Eggs are incubated for approximately 12 days, and nestlings are fed by both parents at the... Wikipedia →

Rare
Under 5% of wildlife watchers report a Medium Tree-Finch sighting in Galápagos Islands on a given day, based on 320 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 70th 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 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Medium Tree-Finch in Galápagos Islands on a given day, against under 5% in August to June, the lowest months. That is one of Galápagos Islands's driest months, with almost no rain against 50 mm in March.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Medium Tree-Finch sightings with a recorded time, and about 8 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 Medium Tree-Finch sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Camarhynchus
The closest relatives of the Medium Tree-Finch that you can see in Galápagos Islands (genus Camarhynchus, Tree-Finches) are Small Tree-Finch (about 30%), Woodpecker Finch (about 10%) and Large Tree-Finch (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Medium Tree-Finch is recorded against all the birds logged in Galápagos Islands (320 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.
