Michigan sits near the northern limit of the Virginia opossum’s range, yet the state’s 1,319 records are anything but sparse. They concentrate across the southern Lower Peninsula, from Kent County east through Washtenaw, Oakland, and Wayne, a farm-and-city landscape where river corridors, woodlots, and milder urban winters suit a thin-furred animal that never adapted to deep cold.
A marsupial working the waterways
The opossum is North America’s only marsupial, and females carry their young in a pouch until the litter is big enough to ride on her back. It is a nocturnal omnivore that walks streambanks and field edges eating almost anything, from insects and carrion to fallen fruit. Michigan’s record follows that habit. Shiawassee National Wildlife Refuge and the marshes around Saginaw Bay anchor the wet-woods core, Detroit River International Wildlife Refuge holds records along a metropolitan waterway, and reports reach north to Manistee National Forest and Sleeping Bear Dunes National Lakeshore.
A calendar keyed to the breeding season
Opossums do not hibernate, though they den up during the worst cold snaps, and their bare ears and tails often carry frostbite scars by spring. Michigan’s counts rise sharply in February and March, when the breeding season sends males roaming, and crest again in May, as females with pouch young and newly independent juveniles start turning up along roads and trails.
Status in Michigan
NatureServe ranks the Virginia opossum S5, Secure, in Michigan, and the species is native to the state. USGS NAS does not list it as nonindigenous here.
