The lesser dog-like bat (Peropteryx macrotis), also known as Peters' sac-winged bat, is a species of bat from South and Central America. First described in 1826, it was renamed in 1843 because the original scientific name was already in use for another species.
The lesser dog-like bat is a small bat, measuring about 6 cm (2.4 in) in head-body length, with a tail about 1.4 cm (0.55 in) long. Adults weigh only about 4 g (0.14 oz), although females are larger than males. They have moderately long fur, which can vary from brown to grey, or even reddish. While it is the smallest of the dog-like bats, it shares with them the long, hairless, snout that is the source of their common name. Apart from the smaller size, it can also be distinguished from its close relatives by possessing an outward-opening glandular sac on the part of the wing membrane forward of the arms.
Lesser dog-like bats are found in the south from eastern Veracruz and Oaxaca in Mexico, throughout Central America. In South America, they are found throughout Colombia, but otherwise only east of the Andes, reaching eastern Bolivia, northern Paraguay, and Santa Catarina in Brazil... Wikipedia →

With luck
About 10% of wildlife watchers report a Lesser Dog-like Bat sighting in Sian Ka'an Biosphere Reserve on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 11 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.
March and September
In those months about 30% of wildlife watchers report a Lesser Dog-like Bat in Sian Ka'an Biosphere Reserve on a given day, against under 5% in April–July and November–January, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Lesser Dog-like 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 Sian Ka'an Biosphere Reserve, in our data
Sian Ka'an Biosphere Reserve is the only park on Wallace's Line with enough records to rate Lesser Dog-like Bat sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Lesser Dog-like Bat is recorded against all the mammals logged in Sian Ka'an 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.
