Sri Lankan Sloth Bear (M. u. inornatus) in Kumana National Park, Sri Lanka (Gaurika Wijeratne) (Creative Commons License)
Sloth bears are found in Sri Lanka, India, Bhutan and Nepal, predominantly in lowland areas. There may still be bears in the wet forests of Bangladesh but this is by no means certain. They inhabit both dry and moist deciduous forests and grasslands.
Mostly nocturnal the bears are omnivorous with termites and ants the main constituents of their diet. The bears use their claws to open the insects’ mounds and nests, sucking them up through a gap in their front teeth. They are also very fond of honey, hence their alternative name of “honey bear”.
Sloth bears do not hibernate and whilst solitary, except for mothers with cubs, seem to tolerate one another in shared ranges. Length varies from 140 to 190 centimetres. Males weigh between 80 and 140 kilograms, and females between 55 and 95 kilograms.
Mating mainly occurs in May, June and July with gestation taking six to seven months. The young are born in earth dens and litters are usually of one or two cubs although litters of three cubs have been reported. The young remain with the mother for upwards of two years. Unique amongst bears, the cubs often ride on their mother’s back.
Sloth bears are classed as vulnerable with a decreasing population due to habitat loss and poaching. Longevity is from 20 to 25 years.
