activity
Activity patterns. Merriam’s Chipmunk is terrestrial and diurnal with bimodalactivity; one peak in the morning and the other in the afternoon. It is active year-round, except at very high elevations, where it hibernates. When wateris scarce, behavioral adjustments and physiological responses to conserve water. Merriam’s Chipmunk sometimes uses burrows and tree cavities of other species, such as woodpeckers and ground squirrels, to build its nest. Tree nests appear to be preferred for rearing young.
