Cinereus shrews live beneath the leaf litter, moss, and woody debris of Maine forests from the coast to the North Woods. Their minute size and near-constant search for invertebrate prey keep them mostly hidden; a quick rustle beside a damp trail is a more likely encounter than a clear view.
They are active throughout the year, using spaces under snow as winter hunting cover. Maine records are concentrated in late summer, especially August and September, and are dominated by GBIF data, a sign that specimen and survey work, not casual sightings, drives the apparent seasonal pattern.
