Cotton mice carry a NatureServe S5 secure rank in South Carolina, and the record leans almost entirely on GBIF specimen data (191 of 191 records, with only 6 also appearing on iNaturalist), meaning trapping surveys, not casual photographs, built nearly the entire dataset for this common Peromyscus mouse.
March alone accounts for 52 of the 191 records, more than a quarter of the year’s total, with August close behind at 30; that pattern likely tracks the timing of concentrated trapping surveys across Congaree National Park and Sumter National Forest rather than any dramatic real seasonal shift in the mouse’s own activity, since records nearly vanish from September through December.
