European rabbits aren’t native anywhere in North America, and Massachusetts’ 17 records almost certainly trace back to domesticated pets that escaped or were released rather than a wild, breeding population. The species is the ancestor of every domestic rabbit breed, which is part of why the IUCN lists it Endangered globally even as escaped and feral populations turn up in places like Cape Cod National Seashore and Parker River National Wildlife Refuge.
The handful of records cluster from May through August, too few and too concentrated in one part of the year to describe a real breeding pattern rather than simply when a loose pet is most likely to be noticed outdoors. NatureServe treats the species as exotic in Massachusetts rather than assigning it a conservation rank here.
