Habitat• The eastern grey

squirrel lives in the upper branches of trees in dense forests. They live here because of the food and shelter provided by the dense vegetation.

Diet

• The grey squirrel is an opportunist when it comes to food but it typically eats buds of trees, seeds, nuts, insects, eggs and apples.

• The grey squirrel hoards hundreds of nuts over the coarse of the year for use in winter. They reclaim these stashes using smell and their excellent spatial memory.

Mating

• There are two breeding seasons each year: Winter and Summer.

• Courtship begins when a female continuously calls down from a tree top with quack-like calls

• Males then fight to determine who is dominant and then chase the female in the tree tops.
