Northern pika (Ochotona hyperborea) During the summer, the fur of northern pikas is light brownish-red and gradually becomes redder along the sides. The belly is reddish-white. In the winter months the fur is much grayer with a hint of brown colouration.
Species of Ochotona are similar in body mass and morphology. Northern pikas range in length from 127 to 186 mm, with a tail length of 50 to 120 mm. Sexes are monomorphic and hard to distinguish. The fur is long, dense, soft and fine. Pikas have rounded ears that are about as wide as they are high. Their legs are short; the hind legs are only slightly shorter than their forelimbs. They have five fingers and toes and the feet are heavily furred on the underside.
