Why must voles feed frequently throughout the day?
Answer
To meet their high metabolic needs relative to their small body mass
Voles possess a high metabolic rate, which is common for small rodents. To maintain this metabolism and sustain their small body mass, they must constantly consume food. This high caloric requirement means that even a small population of voles can rapidly deplete vegetation in an area. Their frequent feeding is an essential biological requirement for survival rather than a social behavior or a strategy related to hibernation.
