Description 4
Voles and cotton rats usually live in different geographic regions, but both groups of small rodents eat grass and make runways. Yellow-nosed Cotton Rats are especially vole-like because they are small and live in grassy patches of habitat in mountains. They are found on isolated mountains at all elevations, sometimes using surface nests and sometimes building them underground. They have 2-6 young in a litter, at almost any season of the year except during the driest part of the summer. The young nurse for about 15 days, but in just over a week, they are also beginning to eat grass.
