| Volcano Deermice are found in open pine forests high in the mountains of Central Mexico's transvolcanic belt, where the summer are wet and the winters are dry and cold. Grass grows in clumps under the pines. The mice scurry between the clumps and have no need to build runways. They dig simple burrows in well-drained areas, or use pocket gopher burrows. They do most of their above-ground foraging after dark, before midnight. Volcano Mice have soft, dense fur and nearly hairless ears. Females can have two or three litters of 2 to 5 a year. The young reach reproductive age in a few months.
Scientists studied a mountainside where a volcano had erupted about 20 years before. Although the habitat was returning to normal, it appeared that no mice had come back to live there.
