Connecticut’s open databases hold 243 records for the meadow vole, split between iNaturalist and GBIF, with sightings logged in every month of the year, a pattern that sets this species apart from several of the state’s other small grassland mammals.

Runways through the grass, not burrows in the woods

Meadow voles live in dense grass and marsh vegetation, the same kind of wet meadow and tidal-marsh edge fringing Hammonasset Beach State Park and the floodplain grassland of the Connecticut River Valley that shelters several of the state’s other grassland small mammals. Rather than digging deep burrow systems, a vole cuts a maze of narrow surface runways through matted grass, tunnels roofed by the vegetation itself that it uses to move, feed, and hide from predators without ever fully leaving cover.

Active straight through the year, not hibernating

Unlike the jumping mouse sharing some of the same marsh edges, the meadow vole doesn’t hibernate, and records reflect that: they’re recorded in every month, dipping in the colder months but never disappearing from the data the way a true hibernator’s records do. That year-round activity, plus a fast breeding cycle that can produce several litters in a single season, makes the meadow vole one of the most frequently recorded prey species for the hawks, owls, foxes, and snakes that hunt Connecticut’s grasslands.

Status in Connecticut

NatureServe ranks the meadow vole S5, secure, and it’s native to Connecticut, most frequently recorded in the state’s grassy lowlands and marsh edges.
