NatureServe ranks the gray wolf SX, Presumed Extirpated, in Maryland, meaning the state’s small number of records almost certainly represent historical specimens, misidentifications, or animals well outside any current range rather than a living population. Wolves were eliminated from the Eastern Seaboard by the early 1900s through hunting and habitat loss.

What sightings exist cluster in January and December, though with the species presumed gone from the state, this pattern reflects when old records were logged rather than any true seasonal activity.
