As they are nocturnal and reputed to be rather shy, everyone agreed that they would be very difficult to see anywhere and certainly not a species that we would be promising to find! The Finland tour was the most popular suggestion as a possibility but someone said that they also occur in Belarus, which is a new tour destination for Avian in 2011.
The talk was exclusively about Russian (or Siberian) Flying Squirrels (Pteromys volans). However, worldwide, there are actually 44 species of Flying Squirrels and the answer to the original question was that one had already been seen on an Avian Adventures tour and quite recently. And we have the pictures to prove it!
This Northern Flying Squirrel (Glaucomys sabrinus) was one of the stars of this year's Avian Adventures tour in Montana and Wyoming.
Found in coniferous and mixed forests, Northern Flying Squirrels are normally nocturnal and arboreal but this one had located an easy meal at ground level in the form of sunflower seeds at a feeder just outside Yellowstone National Park.There are just two Flying Squirrels in the New World, the other (not surprisingly) is called Southern Flying Squirrel (Glaucomys volans), although it mostly occurs in the eastern USA.
Of course Flying Squirrels can't really fly but with the aid of their patagium, a furry parachute-like membrane that stretches from wrist to ankle, they do glide remarkable distances from tree to tree - "flights" by some species of as much as 90 metres have been recorded. Typical of many nocturnal creatures, they have large bulging eyes.
Pretty cute!
