They are about the size of a small rabbit, and look kind of like Guinea Pigs. They have a trill call, that sounds like a tiny telephone.
General information about
Ground Squirrel :
The ground squirrel is especially renowned for its tendency to rise up on its hind legs. It does this whenever it senses nearby danger, or when it must see over tall grasses. The squirrel then curls its paws flat against its chest and sends a screeching call to warn other family members about the presence of predators. The scientific name of this genus means "seed-lovers".
Though capable of climbing, most species of ground squirrel live in open, treeless habitats. They are sometimes called Marmots, but that is incorrect.
