Mops pusillus is a species of bat in the family Molossidae. It is found on islands off the coast of east Africa. This bat was originally considered a distinct species, before being relegated to a synonym of M. pumilus. However, the presumed Seychelles populations of M. pumilus were discovered to be smaller than the ones in Kenya and Madagascar, leading to the resurrection of the name as a distinct species.
The bat has a blackish-brown dorsum, brown throat, and dark brown chest. It has a dark brown venter, with a small white mid-ventral patch in rare cases. Comorian populations of the bat have a distinct whitish or beige strip of hairs at the base of the wings.
There is a possibility of inter-island seasonal variation in reproduction. The bat is found in the Comoro Islands and Seychelles. On Comoros, it was not observed roosting in natural sites, but instead mostly in the attics of public buildings. Moreover, the bats were observed to roost in older-style colonial buildings, but not in modern buildings. Their roosting may also be seasonal, as they have been observed abandoning roosts during the cold season. Wikipedia →

With luck
About 10% of wildlife watchers report a Seychelles Free-tailed Bat sighting in iSimangaliso Wetland Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 31st most-seen of the 34 mammals we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January, March, August and October
In those months about 10% of wildlife watchers report a Seychelles Free-tailed Bat in iSimangaliso Wetland Park on a given day, against under 5% in February, April–July, September and November–December, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Seychelles Free-tailed 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 iSimangaliso Wetland Park, in our data
iSimangaliso Wetland Park is the only park on Wallace's Line with enough records to rate Seychelles Free-tailed 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 Seychelles Free-tailed Bat is recorded against all the mammals logged in iSimangaliso Wetland Park (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.
