The cyclops roundleaf bat or cyclops leaf-nosed bat (Doryrhina cyclops) is a species of bat in the family Hipposideridae found in the forests of equatorial Africa. It is placed in the genus Doryrhina together with the closely related greater roundleaf bat (Doryrhina camerunensis).
Cyclops roundleaf bats are relatively small, with adults ranging from 10 to 13 centimetres (3.9 to 5.1 in) in total length, including a tail approximately 3 centimetres (1.2 in) long. With an average weight of 35 grams (1.2 oz), females are significantly larger than males at just 29 grams (1.0 oz). The body is covered in thick woolly fur, which is a dark brown in colour, grizzled with lighter flecks on the tips of the hairs. The wings are very dark brown, almost black, in colour.
The ears are long and narrowly pointed. The nose-leaf has a distinctive shape, with a rounded horseshoe shape over the muzzle and a posterior leaf with two projections on each side. Both parts of the leaf also possess small club-like structures projecting from their mid-line. The "cyclops" part of the bat's name comes from the presence of a narrow circular opening in the centre of the forehead, just behind, and normally... Wikipedia →

Likely
About 40% of wildlife watchers report a Cyclops roundleaf bat sighting in Taï National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 14 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
August
In that month about 60% of wildlife watchers report a Cyclops roundleaf bat in Taï National Park on a given day, against about 10% in April–May, July and September, the lowest months. October to February have too few records to rate.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Cyclops roundleaf bat sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Taï National Park, in our data
Taï National Park is the only park on Wallace's Line with enough records to rate Cyclops roundleaf bat sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cyclops roundleaf bat is recorded against all the mammals logged in Taï National Park (5 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.
