European rabbits aren’t native anywhere in North America, and Massachusetts’ 9 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 animals turn up in counties from Essex on the North Shore to Barnstable on Cape Cod.
The handful of records lean toward July and 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.
