"In North America, black squirrels are uncommon, with one estimate putting them at a rate of one in every 10,000 squirrels."

The authors certainly haven't been to SE Michigan. We have thousands of black squirrels. I see them most every day. They've been here quite a while, too. I remember telling my young daughter (now 40) bedtime stories about black squirrels.
