Flying Squirrel Visits Carlsbad Art Farm


Art Farm Summer Camp Aide Max Giffen delighted campers recently by bringing an unusual visitor to natural science class -- her pet flying squirrel Persephone. If you click on the picture, you can catch a glimpse of Persephone at the bottom of her travel cage.

One surprise about flying squirrels is that they're pretty small compared to the more robust ground and tree squirrels we're accustomed to in California. Max noted that to be aerodynamic, flying squirrels need to be small enough to glide from destination to destination. Persephone is a variety found in North America (there are two). In all, world wide, there are 44 known species.

Flying squirrels are not capable of sustained flight. Instead they glide between trees, with flights recorded up to 295 ft. The direction and speed of the animal in midair is varied by changing the positions of its two arms and legs, largely controlled by small wrist bones. This changes the tautness of a furry parachute-like membrane that stretches from wrist to ankle. It has a fluffy tail that stabilizes in flight. The tail also works as an airbreak before landing.

Also, unlike other squirrels, flying squirrels are nocturnal. Their large eyes indicate the importance of vision as they navigate and forage at night. Because of their small size and elusive behavior, flying squirrels are difficult to observe, which is why this class felt very fortunate to observe a tame one up close. Students took notes and drew pictures of Persephone in their nature journal.
