Flying squirrels are capable of gliding and one of the least known mammals of the world. Work on these animals is less and sporadic due to their crepuscular and cryptic habits. At the present scenario, a complete pilot study is in an urgent need to formulate conservation strategies and policies to conserve them in India. Therefore, a thorough review on biology and conservation status of flying squirrels in India is provided here. A total of 13 species of flying squirrels present in India i.e., Belomys pearsonii, Biswamoyopterus biswasi, Eupetaurus cinereus, Eoglaucomys fimbriatus, Hylopetes alboniger, Petaurista elegans, P. mishmiensis, P. magnificus, P. mechukaensis, P. nobilis, P. petaurista, P. philippensis and Petinomys fuscocapillus, wherein three are endemic to the country. P. philippensis has broader distribution and is found to be more studied than others. Eastern part of the country contains the highest species number (n = 10) follows three in northern part, two in southern part and one in western part subsequently. All species are facing threat to their population due to native habitat loss, degradation and hunting. Harmonization, alliances and partnership between various stakeholders along with better application of standard techniques would be strengthen to develop conservation strategies and implementing their coordinated actions could preserve flying squirrels’ future in the country landscape.
