Eastern grey squirrels, depending on the area, are either black or grey. Native to North America, they are important members of the forest ecosystems in which they live. They eat a lot of seeds. Their seed-caching activities may help disperse tree seeds and they are considered one of Mother Nature’s best foresters.
Red squirrels, unlike the eastern grey squirrel, are more territorial and solitary by nature. These squirrels are very vocal and can be heard chattering and scolding to alert nearby creatures of their presence. They are most commonly seen in the fall when they are busy collecting pine cones and other seeds for winter.
Grey and red squirrels are not reproductively compatible.
