Book Description
Excerpt from Estimating Muskrat Populations by House Counts For survival, muskrats depend largely on concealment and a consider able part of their existence is spent in underground tunnels and burrows, inside Of their nests and feeding shelters, in swimming, and in digging loose and gnawing on the subterranean roots of various aquatic marsh or swamp plants. For this reason their presence on an area is detected by evidence of their activity rather than on actual observation of the animals themselves. Muskrat signs may take the form of narrow channels or runs leading through the marsh to and from nesting sites and nearby feeding grounds, air bubbles under ice, bank burrows and tunnels, plant cuttings.
