Vermont’s occurrence records list 504 documented short-tailed shrew sightings, all drawn from GBIF specimen and survey data rather than casual photographs. This species spends most of its life under leaf litter and in shallow burrows, so records lean almost entirely on live-trapping surveys rather than sightings.

A leaf-litter hunter across Vermont’s hardwood floor

Records cluster in the Green Mountains and the Green Mountain National Forest, where the moist duff layer beneath Vermont’s northern hardwood forest gives a short-tailed shrew the tunnels and cover it needs to hunt earthworms, insects, and snails almost around the clock. That same forest floor runs across most of the state, so the concentration in the mountains likely reflects where small-mammal trapping surveys have looked hardest, not a real limit on the shrew’s range.

A late-summer spike tied to survey season

Records climb through August and September, the stretch of the year when small-mammal trapping studies run most often and when young shrews weaned earlier in the summer disperse to find their own territory. A short-tailed shrew has one of the highest metabolic rates of any mammal its size and has to eat nearly its own body weight in food most days, driving it to hunt constantly rather than den up for long stretches.

Status in Vermont

NatureServe ranks the short-tailed shrew S5, secure, and it’s native to Vermont. Because it rarely surfaces in daylight, most of what’s known about its numbers in the state comes from these trapping records rather than casual sightings.
