Summary
On 26 May 2016, whilst spotlighting alone along Power Station Road in Kinabalu Park (Borneo, Malaysia) I photographed a Whiskered Flying Squirrel (Petinomys genibarbis) very close to the 4 Km post and at an elevation of approximately 1840 m. This appears to be a notable elevation record; and possibly the first photographs in the wild.
