Merriam's Pocket Mouse Perognathus merriami
It is found in northeast Mexico and New Mexico, Oklahoma and Texas in the United States. It is mainly nocturnal and spends the day in a shallow burrow with several entrances. At temperatures below 10 °C (50 °F) Merriam's pocket mouse becomes torpid and in some parts of Texas it may become dormant or hibernate in winter. The diet consists primarily of seeds which it carries back to its burrow in its cheek pouches and consumes there, leaving a littering of husks on the floor.
