The Florida bonneted bat or Florida mastiff bat (Eumops floridanus) is a species of bat in the genus Eumops, the bonneted bats or mastiff bats. Until recently, it was classified as a subspecies of Wagner's bonneted bat (Eumops glaucinus). It is endemic to southern Florida in the United States.
This species has one of the smallest geographical distributions of any New World bat. It has been called "one of the most critically endangered mammal species in North America". It is protected under the Endangered Species Act.
The earliest bonneted bat fossil was discovered in 1922 in Melbourne, Florida. The fossil consisted of a preserved jawbone that dated back to the Pleistocene; its similarity to genera Eumops and Molossus was noted, but it was initially placed into a new genus, Molossides, due to what appeared to be a unique dental formula. The fossil was reclassified into the genus Eumops in 1963 on the belief that the original fossil did not show a bat with a single lower incisor, but rather the fossil jaw was missing an incisor and the species actually had two lower incisors.
A live bonneted bat was first recorded in Florida in 1936, from an individual collected from a... Wikipedia →

Rare
Under 5% of wildlife watchers report a Florida Bonneted Bat sighting in Everglades National Park on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 17 mammals 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.
May–June and August
In those months about 10% of wildlife watchers report a Florida Bonneted Bat in Everglades National Park on a given day, against under 5% in July and September–April, the lowest months. Those are among Everglades National Park's wettest months, with about 190 mm of rain a month against 40 mm in March.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Florida Bonneted 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.
Only Everglades National Park, in our data
Everglades National Park is the only park on Wallace's Line with enough records to rate Florida Bonneted Bat sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Florida Bonneted Bat is recorded against all the mammals logged in Everglades National Park (38 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.
