Minnesota’s records for the white-footed mouse run to about 1,300, concentrated along the wooded river corridors that cut through the Twin Cities metro. That pattern reflects where researchers have trapped and photographed the animal, in city parks and greenways, rather than how many mice actually live in the state’s woodlots and brush.

Along the Mississippi and Minnesota rivers, narrow bands of forest, brush, and wetland thread through dense suburbs and the urban core, and the white-footed mouse does well in exactly that kind of fragmented habitat. It climbs readily and nests in stumps, brush piles, and tree cavities, and it’s one of the small mammals most often turned up in surveys of Twin Cities regional parks and river greenways, even where the surrounding land is heavily developed.
Why summer dominates the record count
Records climb sharply from May through August, then fall away almost to nothing by winter. Mice keep breeding through the warm months, and the young born in early summer start showing up in traps and on trail cameras as they disperse in July and August. Once snow covers the ground, mice stay active but mostly out of sight, moving through tunnels under the snow or into brush piles, wood stacks, and sometimes buildings, where they wait out the cold.
Status in Minnesota
The white-footed mouse is native to Minnesota. NatureServe lists it SNR here, unranked at the state level, while it carries a secure G5 rank globally.
