The BBC has a recording of a chipmunk's sound.Īccording to New Hampshire Public Television, the name "chipmunk" comes from the "chip-chip" sound the creature makes.Ĭhipmunks require colder temperatures to hibernate.

The Buller's chipmunk is only found in Sierra Madre in south Durango, west Zacatecas and north Jalisco, Mexico. This classification is due to population decline and distribution fragmenting. The Buller's chipmunk, Tamias (Neotamias) bulleri, is the only species listed as vulnerable. Their population decline is due mostly to the invasion of humans in their habitat and domestic cats killing chipmunks in large numbers. The Palmer's chipmunk, Tamias (Neotamias) palmeri, is found only on one small mountain range, the Spring Mountains in southwestern Nevada. Some studies have suggested that these should be separate genera.Īccording to the IUCN's Red List, only one chipmunk species is endangered.
