Who it is

• Scientific name: Sciurus carolinensis
• Family & relatives: A tree squirrel in the family Sciuridae, related to other tree and ground squirrels, chipmunks, marmots, and prairie dogs.
• How to spot it: A slim gray rodent with a bushy tail nearly as long as its body, small rounded ears, and a pale to white belly.

Its body & abilities

• Size: Head and body about 23 to 30 cm, with a tail of roughly 19 to 25 cm.
• Weight: Usually about 400 to 600 g (14 to 21 oz).
• Body & adaptations: Its ever-growing front teeth gnaw nuts and bark, sharp claws grip bark, and its bushy tail helps it balance and keeps it warm.
• Top speed: Can scamper along the ground and up trees at about 20 km/h (12 mph).
• Strength: A remarkable climber and jumper, it can leap several times its own body length between branches and land safely.
• Senses: Sharp eyesight well suited to spotting movement, plus a keen sense of smell it uses to find buried nuts.
• Growing up: Pups are born tiny, blind, and furless, open their eyes at about four weeks, and are ready to live on their own by around ten to twelve weeks.

Where it lives

• Habitat: Woodlands and forests with plenty of nut-bearing trees, and very much at home in city parks and gardens.
• Where in the world: Native to eastern North America, and introduced by people to Britain, Ireland, Italy, and parts of western North America.
• Territory: It keeps a loose home range of a few hectares that overlaps with its neighbors rather than a strictly guarded border.

What it eats

• Diet: A mostly plant-eating omnivore that drinks from puddles, streams, and dew.
• Favorite foods: Nuts, acorns, seeds, buds, flowers, and fruit, plus the occasional insect, egg, or fungus.
• How it hunts: It forages rather than hunts, gathering nuts and burying them one by one to dig up and eat later in winter.

How it behaves

• How it moves: Darts and climbs with ease, running headfirst down tree trunks by turning its back feet around to grip.
• When it is active: Active by day, especially in the morning and late afternoon, and stays awake all winter instead of hibernating.
• Family life: Fairly social and often seen together, though each squirrel forages on its own; a group is called a scurry or a dray.
• How it talks: Chatters, barks, and flicks its tail to warn others of danger and to signal how it feels.
• Babies: After about a 44-day pregnancy the female bears a litter of around 2 to 4 pups in a leafy tree nest called a drey, and raises them alone.

Its place in nature

• Role in nature: A key seed planter whose forgotten buried nuts grow into new trees; hawks, owls, foxes, and snakes are among its predators.
• Conservation: Listed as Least Concern by the IUCN, with a large and thriving population across its range.
• Dangers: Many are caught by predators or lost to cold winters, disease, and busy roads, especially when young.

Life & legacy

• How long it lives: Often just 1 to 2 years in the wild because of predators, but up to around 12 years for those that survive.
• In our culture: A familiar and much-loved park visitor, famous for its playful antics and its habit of stashing nuts.
• Where to see it: Almost any wooded park, garden, or forest in the eastern United States, plus parks in Britain and other places it was introduced.
• Fun fact: A squirrel sometimes digs fake holes and pretends to bury a nut to trick thieves who might be watching.
