Chipmunks Will Stuff Food into Their Cheek Pouches to Carry

Chipmunks will stuff food into their cheek pouches to carry back to their burrow. Giraldeau and Kramer (1982) found that laboratory chipmunks

A) carried seeds from seed trays (patches) in their cheek pouches only when the distance to the burrow was great; otherwise, they simply carried individual seeds one at a time.
B) spent less time at a seed tray when the distance between the seed tray (patch) and the burrow was increased.
C) spent more time at a seed tray when the distance between the seed tray (patch) and the burrow was increased.
D) were unable to adjust their food loads with varying distances between the seed tray (patch) and the burrow because of the physical constraints on the size of their cheek pouches.
