"Southern Flying Squirrels Land in Canada"

"What happens when a Southern flying squirrel meets a Northern flying squirrel, and the mood is just right?"



"A decade ago, the answer would have been nothing. But more recently, Canadian wildlife researchers collected DNA evidence showing the two species can and do interbreed, as the Southern flier's habitat moves northward.

The result is a hybrid offspring, with the Southern squirrel's shorter body and the Northern squirrel's gray-white belly fur. Some who hail from the north have suggested calling it the "Canadian" flying squirrel."
