Oklahoma’s 243 records for the southern short-tailed shrew come with an asterisk the size of a county: 234 of them are from Le Flore County, in the Ouachita Mountains of the state’s southeast. McCurtain County adds 4, Tulsa 3, and Choctaw and Bryan 1 each. A skew that extreme is the signature of long-running survey work in one place, not proof that the rest of Oklahoma lacks the shrew. Still, the cluster lands exactly where habitat says it should: the forested ridges and clear streams of the Ouachita and Kiamichi country, where Beavers Bend State Park, Robbers Cave State Park, and the national forest hold the deep leaf litter this species hunts under.
A venomous little hunter that never slows down
Short-tailed shrews are among the few venomous mammals, using toxic saliva to subdue prey, and they run such a fast metabolism that they must feed every few hours. That life doesn’t pause for winter, and Oklahoma’s calendar agrees: records appear in every month, cresting in July with 50, with a smaller April and May rise and another bump in November. Trapping effort shapes those numbers, but the year-round presence is real.
Imperiled despite the record pile
Here’s the useful caution: 243 records sound like abundance, yet NatureServe ranks the species S2 in Oklahoma, imperiled. The rank reflects how narrow its confirmed state range is, essentially one mountain region at the edge of its broader eastern distribution. Records measure where people looked, and Oklahoma has looked hardest in exactly one corner.
