Spend about half their time sleeping in their deep tunnel system nests. Although moles are typically referred to as an insectivore, they are more of an omnivore. They eat methodically on earthworms and soft-bodied insects but will consume vegetative matter as well as other rodents and even birds. Since worms offer so little calories per serving, they are forced to consume masses of them to survive. Moles will also clip the worm's head off and roll the remainder up in a deep food storage vault for later consumption, generally when temperature and soil conditions limit high energy.
Populations generally vary with soil and food conditions.
Territories will overlap and can be almost 20 times the area of a pocket gopher home range. Prefer lighter more friable soils with corresponding benefit of good gas exchange and higher population of target foods. Breeding follows improved food and temperature conditions. Males will construct and maintain overlapping systems to adjoining female tunnel systems during this cycle. Males will build large radial systems to overlap female home ranges.
