Sciurus
Sciurus is a genus of tree squirrels in the family Sciuridae. Its species include the eastern gray squirrel and the Eurasian red squirrel.
Sciuridae: Sciuridae is the family of rodents that includes squirrels, marmots, and chipmunks. Sciurus is one genus within this broader squirrel family.
Eastern gray squirrel: The eastern gray squirrel is a North American tree squirrel, Sciurus carolinensis. It is one of the best-known species in Sciurus.
Squirrel caching behavior: Squirrel caching behavior is the storing of food for later consumption, often in scattered locations. Sciurus species commonly bury or conceal food, especially seeds and nuts.
Seed dispersal: Seed dispersal is the movement of seeds away from the parent plant, enabling plant reproduction and range expansion. Forgotten Sciurus food caches can germinate and move tree seeds.
Sciurus versus Tamiasciurus: Tamiasciurus is a genus of North American tree squirrels that includes red squirrels and Douglas squirrels. It is a separate tree-squirrel genus often confused with Sciurus species.
Rodent: Rodents are mammals characterized by a single pair of continuously growing incisors in each jaw. Sciurus belongs to the mammalian order Rodentia.
Eurasian red squirrel: The Eurasian red squirrel is a reddish tree squirrel, Sciurus vulgaris, found across parts of Europe and Asia. It is another widely recognized member of the genus.
Scatter-hoarding: Scatter-hoarding is the storage of food in many separate caches rather than one central store. Some Sciurus squirrels use dispersed caches that can later support seed germination.
Urban wildlife: Urban wildlife comprises non-domesticated animals living in or around cities and towns. Eastern gray squirrels are common urban members of Sciurus.
Flying squirrel: Flying squirrels are gliding rodents in the tribe Pteromyini, with a membrane between their limbs. Unlike Sciurus, they glide between trees rather than relying on ordinary leaps.
