Spix's disk-winged bat (Thyroptera tricolor), is a species of bat in the family Thyropteridae. It is native to the Americas from Mexico to Brazil. The most prominent anatomical feature of this bat, which distinguishes it from other species, is the disks on its thumbs and hind feet. These circular disks act as suction cups, allowing the bats to cling onto and move along smooth surfaces.
Spix's disk-winged bat is distributed in the nations of Venezuela, Tobago, Trinidad, Suriname, Peru, Panama, Mexico, Guyana, Guatemala, Honduras, French Guiana, Costa Rica, Ecuador, Colombia, Brazil, Belize, and Bolivia. It has a patchy distribution but a very wide range, and it is considered to be a least-concern species by the International Union for Conservation of Nature (IUCN).
Species abundance of the bat may be limited by the availability of roosting sites. Whereas other species of bats are capable of aggregating in large numbers, hanging head-down by their toes from cave ceilings and hollow trees, T. tricolor is adapted to roosting in furled leaves, and its populations may be limited by the abundance of plants with this feature.

Possible
About 20% of wildlife watchers report a Spix's Disk-winged Bat sighting in Corcovado National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 31 mammals we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August
In that month about 30% of wildlife watchers report a Spix's Disk-winged Bat in Corcovado National Park on a given day, against under 5% in April–May and September–November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Spix's Disk-winged Bat 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 Corcovado National Park, in our data
Corcovado National Park is the only park on Wallace's Line with enough records to rate Spix's Disk-winged Bat sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Chiroptera
The closest relatives of the Spix's Disk-winged Bat that you can see in Corcovado National Park (order Chiroptera, Bats) are Great Fruit-eating Bat (about 10%), Thomas's Shaggy Bat (about 10%) and Chestnut Sac-winged Bat (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spix's Disk-winged Bat is recorded against all the mammals logged in Corcovado National Park (20 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.
