Скачать или смотреть Chipmunk chirping sound.

The chipmunk's feeding habits reflect the woodland's seasonal supply of seeds, fruits, nuts, fungi, and tubers. Of this supply, striped, red and sugar maple seeds, beechnuts, the fruit of black cherries, and yellow trout lily bulbs form the bulk of the diet. Chipmunks prefer beechnuts, and can stuff their two internal cheek pouches with as many as 32 of the husked nuts at one time for transport to an underground cache, which by the end of autumn may contain 5000-6000 nuts. When the beechnut crop is poor, rough barked maple trees serve as “ladders” for entry to the canopy of mature beech trees whose smooth bark acts as a barrier to this “ground squirrel”. Once in the canopy, chipmunks locate cluster of beechnuts by sight and then nip them off, returning to the ground a few minutes later to retrieve them. During years of abundant beech mast, nuts are gathered from leaf litter by ground foraging.

Chipmunks are quite vocal, producing loud “chips,” “chip-trills,” and soft “cuk-cuk-cuk...” calls which function to announce the intrusion of predators, and to advertise occupied areas. The same calls accompany aggressive encounters. High intensity chases with frequent reversals establish temporary hierarchies among small groups of males competing for access to females in estrous. Chases may lead to fighting in which opponents bite each other. Rushing, chasing, and particularly posturing, e.g., flattening the ears, moving jerkily, and erecting the tail hairs, provide important visual cues to motivation. Chipmunks touch noses and sniff each other's hindquarters during some encounters, responding to chemical signals such as those produced by secretions of the anal glands.
