What Is a Blue Squirrel
A blue squirrel refers to several squirrel species or individuals with unusual blue-gray or bluish fur tones, often caused by genetics, diet, or lighting. In wildlife reports, the term is sometimes used for certain tree squirrels with darker, blue-tinted coats rather than a single official species.
Habitat and Diet
Blue-gray squirrels typically live in temperate forests, parks, and suburban areas with mature trees. They feed on nuts, seeds, fruits, and bark, and they cache food for winter, helping disperse seeds and supporting forest regeneration.
Conservation and Observation
Most squirrels with blue-tinted fur are not globally threatened, but local populations can decline due to habitat loss and vehicle collisions. To learn more about squirrel ecology and conservation, visit the IUCN Red List of Threatened Species at https://www.iucnredlist.org.
