Males also possess a skin mask that can be used to cover their face. The wrinkle-faced bat has storage pouches in its mouth to allow it to store fruit. C. senex subsp. greenhalli differs from the more common C. senex subsp. senex by being larger and in having a more domed braincase, better developed sagittal crest, and relatively shorter maxillary toothrow. Their skulls are extremely short and wide, which is thought... Wikipedia →

With luck
About 10% of wildlife watchers report a wrinkle-faced bat sighting in Calakmul Biosphere Reserve on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 19 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
November
In that month about 30% of wildlife watchers report a wrinkle-faced bat in Calakmul Biosphere Reserve on a given day, against under 5% in March–May, August–September and December–January, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most wrinkle-faced bat sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 parks where we can rate wrinkle-faced bat sightings, Calakmul Biosphere Reserve has the highest daily chance: about 10%. Next come Monteverde Cloud Forest Reserve (Costa Rica, about 10%).
Same family: Phyllostomidae
The closest relatives of the wrinkle-faced bat that you can see in Calakmul Biosphere Reserve (family Phyllostomidae, New World Leaf-nosed Bats) are Jamaican Fruit-eating Bat (about 10%), Big-eared Woolly Bat (about 10%) and Pygmy Fruit Eating Bat (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the wrinkle-faced bat is recorded against all the mammals logged in Calakmul Biosphere Reserve (8 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.
