Pikas • Herbivore
• Active year round, even in winter
• It survives the cold winter by eating dried vegetation they have stored away in hay piles
• alpine grasses, sedges, thistles, fireweed, cushion plants and lichens
• Food passes quickly though the digestive, system only partially digested
• eat their own feces (waste) to extract more nutrients in the digestion process.

• To determine the difference between Eastern Cottontail and New England Cottontail – In the field compare ear size and body size– New England have smaller ears and bodies– (95%) have a black line on the front edge of the
ear (Easterns 40%)– In the laboratory skull characteristics and
measurements and by DNA techniques.
