December's Question Corner
From the December, 2013 issue
Q. Black squirrels are predominant (or perhaps exclusive) in Ontario. A Canadian friend recently stated that she had heard that they have "crossed over" into Michigan. Do you know the magnitude of this black squirrel migration?
A. Black squirrels are a variant of the Eastern gray squirrel--the gene for the black coat is recessive. The black variety has recently become more common in Ann Arbor.
