Namdapha flying squirrel
|Namdapha flying squirrel|
The Namdapha flying squirrel (Biswamoyopterus biswasi) is an arboreal, nocturnal flying squirrel endemic to northeastern India, where it is known from a single specimen collected in Namdapha National Park in 1981. No population estimate is available for B. biswasi, but the known habitat is tall Mesua ferrea jungles, often on hill slopes in the catchment area of Na Dihing river (particularly on the western slope of Patkai range) in northeastern India.
The scientific name commemorates Biswamoy Biswas (1923–1994).
The Namdapha flying squirrel is listed as "critically endangered. It is known from a single specimen collected in 1981 in Namdapha National Park. Its range of the Namdapha flying squirrel may be restricted to a single valley and it is threatened by poaching of animals for food from within the park, and possibly by habitat destruction. It is among the 25 “most wanted lost” species that are the focus of Global Wildlife Conservation's “Search for Lost Species” initiative.
There are several later reports of sightings by tourists and local researches, but a review by scientists specialising in flying squirrels found that most—if not all—have been the result of confusion with other, more common species that occur in Namdapha National Park, especially the rather similar red giant flying squirrel (Petaurista petaurista ).
