Are there black squirrels?

There are many species of squirrels, and they come in a variety of colors, ranging from red to brown to gray and black. Black squirrels are a melanistic variety of the Eastern Grey Squirrel, and individual black squirrels can exist wherever Grey Squirrels live. Grey mating pairs may produce black offspring, and in areas with high concentrations of black squirrels, mixed litters are common. The black subgroup appears to have been dominant throughout North America prior to the arrival of Europeans in the 16th century, since their dark colour helped them hide in virgin forests which tended to be very dense and shaded. As time passed, hunting and deforestation led to biological advantages for grey coloured individuals. Today, the black subgroup is particularly abundant in the northern part of the Eastern Grey Squirrel's range., probably due to the significantly increased cold tolerance of black individuals, as their dark coat helps them absorb more solar radiation. Large natural populations of black squirrels can be found throughout Ontario, and in several parts of Michigan, Wisconsin and Ohio. Black squirrels can also be found in England, where they are an introduced species.
