Red Squirrel also relies on bird eggs and shoots for their dietary needs. Diet and Nutrition The American red squirrel eats acorns, hazelnuts, seeds from other deciduous trees, shoots, berries, fruit, birds' eggs, and mushrooms. They occasionally eat bird eggs or chicks. Their diet usually consists of pinecone seeds, hazelnut, chestnuts, beech nuts, berries, fungus, and new leaf growth. Sometimes it eats insects, young birds, mice and rabbits. [6] In Yukon, extensive behavioral observations suggest white spruce seeds (Picea glauca) comprise over 50% of a red squirrel's diet, but squirrels have also been observed eating spruce buds and needles, mushrooms, willow (Salix sp.) It will strip conifer cones for the seeds inside, and sometimes strips tree Red squirrels eat mostly the seeds from trees, and will neatly strip conifer cones to obtain the seeds, nuts (particularly hazelnuts but also chestnuts and beech), berries, and young shoots. A large part of its diet is made up of pine seeds. American red squirrels are primarily granivores, but incorporate other food items into their diets opportunistically.

They tend to spend 70 to 80% of their daily time on eating.

The red squirrel eats a wide-variety of foods including insects, seeds, bark, nuts, fruits, mushrooms and pine seeds or cones. … During the summer, American red squirrels collect and hide seeds They largely feed early morning and dusk when their predators find hard to prey them. Diet of the Red Squirrel Red squirrels are mostly herbivorous, but scientists consider them omnivores. In the fall, it will cut green pine cones from trees and store them in the ground. However, they will also eat bird eggs, berries, and fruit when they are available. These species predominantly feed on seeds, trees, fungi nuts, hazelnuts, and fruits like berries. Diet American red squirrels mainly feed on the seeds and cones of evergreen trees. Pine squirrels (Tamiasciurus), like Douglas and American red squirrels, are larder hoarders who eat primarily tree seeds (pine cones); as well as other foods that they can find such as mushrooms, buds, catkins, flowers and berries, storing all of their food in a single location or midden (larder). However, research has shown these creatures will also eat eggs and small mammals on rare occasions.
