The gray slender loris (Loris lydekkerianus) is a species of primate in the family Loridae. It is native to India and Sri Lanka and inhabits subtropical and tropical dry forests and subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Together with the red slender loris (Loris tardigradus), the grey slender loris (Loris lydekkerianus) is a type of slender loris (genus Loris) in the strepsirrhine primate family Lorisidae. In 1908 Spanish zoologist Ángel Cabrera first described the Mysore slender loris (Loris tardigradus lydekkerianus) in Chennai, India, which he named for the English naturalist Richard Lydekker. This subspecies was further described by William Charles Osman Hill in his seminal primate book Primates: Comparative Anatomy and Taxonomy (1953). Hill believed there was one species of slender loris which was further split into six subspecies, two in India and four in Sri Lanka. In 1998 biological anthropologist Colin Groves recognised two species, L. tardigradus and L. lydekkerianus, which have been widely accepted by the scientific community. Loris lydekkerianus now includes four geographically separated subspecies, L. l. lydekkerianus... Wikipedia →

Possible
About 20% of wildlife watchers report a Gray Slender Loris sighting in Minneriya National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 18 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
January–February and October
In those months about 30% of wildlife watchers report a Gray Slender Loris in Minneriya National Park on a given day, against under 5% in March, May–July, September and December, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Gray Slender Loris sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Minneriya National Park, in our data
Minneriya National Park is the only park on Wallace's Line with enough records to rate Gray Slender Loris sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Primates
The closest relatives of the Gray Slender Loris that you can see in Minneriya National Park (order Primates) are Toque Macaque (about 50%), Tufted Langur (about 40%) and Purple-faced Lutung (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray Slender Loris is recorded against all the mammals logged in Minneriya National Park (9 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.
