What characteristic feature helps identify vole locations?

The characteristic feature that helps identify vole locations is narrow runways connecting shallow burrows. Voles are small rodents that create distinctive pathways or runways as they travel between their burrows and feeding areas. These runways often appear as flattened grass or vegetation in areas where voles are active. The shallow burrows indicate their nesting or shelter sites, while the runways provide evidence of their movement patterns. This behavior is typical for voles and distinguishes them from other rodents that may create different types of nests or markings.

In contrast, large mounds of soil are more commonly associated with moles rather than voles. Brightly colored markings on trees might indicate the activity of other animals, possibly pests like beetles or caterpillars, and are not a feature of voles. Frequent vocalizations are not a notable characteristic of voles, as they are generally quieter creatures compared to other rodents that may make more noise. Thus, the identification of voles relies primarily on observing their runways and burrows.
