Types of Mountain Lion in Massachusetts

Mountain lions once roamed across North America from Canada to Florida. European settlers considered them threats to livestock and settlements, so they systematically hunted them to extinction across the eastern United States during the 1800s. By 1900, no wild mountain lions remained east of the Mississippi River. Unlike predators such as coyotes and bobcats, which are highly adaptable and can survive in small forests and near human development, mountain lions require vast territories and large populations of deer or elk to thrive. The fragmented forests of the Northeast and the absence of natural prey populations make natural reestablishment extremely unlikely.

Mountain lions are large, muscular, tan-colored cats that weigh 100 to 200 pounds when fully grown. They have a long, thin tail that can be as long as 3 feet, small rounded ears, and a relatively small head compared to their body size. A full-grown mountain lion is much larger than a bobcat or a coyote. Bobcats weigh only 15 to 30 pounds and have short tails with black tips, tufted ears, and spotted fur. Coyotes weigh 20 to 50 pounds, have gray or reddish fur, and hold their tails low or between their legs when running. A feral domestic cat is obviously tiny, usually under 15 pounds, but a large tom cat in poor lighting can be mistaken for a young bobcat. When sightings are reported in Massachusetts, the animal is nearly always one of these three species.

Coyotes are the most common misidentification. A large coyote with a thick winter coat can seem bigger than it is, and a brief glimpse at night or at a distance can create the illusion of a larger predator. Bobcats are also regularly mistaken for mountain lions, especially if the observer is unfamiliar with how large a 25-pound bobcat looks. Feral and outdoor domestic cats have been the subject of several famous 'mountain lion' reports in New England. Mangy coyotes with patchy fur sometimes appear strange enough to prompt sighting reports. People who have never seen a wild bobcat or coyote often overestimate their size. Motion, shadows, and fear can all amplify misidentification.

Unlikely, but not impossible. Some young male mountain lions from the western United States and the Florida panther population have wandered east, and there have been confirmed sightings in states including Connecticut, New York, and North Dakota. In 2011, a young male mountain lion that likely traveled from the Black Hills of South Dakota was killed in Connecticut. These long-distance wanderers are almost always solitary young males searching for new territory. However, for a breeding population to establish, many more individuals would need to arrive and survive, which requires habitat connectivity, prey abundance, and tolerance from local people. Massachusetts would need sustained habitat restoration and reintroduction efforts far beyond current reality for mountain lions to return.

Massachusetts is home to three native wild predators: coyotes, bobcats, and red foxes. Coyotes are the largest and most common, with populations thriving in forests, swamps, and even suburban areas. They hunt deer, small mammals, and sometimes pets. Bobcats are solitary, elusive cats that hunt rabbits, hares, and rodents and are rarely seen despite their presence throughout the state. Red foxes are smaller and less common than coyotes but are often seen at dawn and dusk. All three are far better adapted to the northeastern landscape than mountain lions would be and play important roles in controlling rodent and herbivore populations.

If you spot what you believe is a mountain lion, bobcat, or coyote, stay calm and maintain distance. Do not approach the animal. Most wild predators avoid humans. If the animal appears sick, aggressive, or is acting strangely, contact the Massachusetts Division of Fisheries and Wildlife at (508) 389-6300 or your local animal control. Take photos or video if safe to do so, note the location, time, and description, and report it. Wildlife officials can help identify the animal and determine if intervention is necessary. Attacks by coyotes or bobcats on humans are extremely rare.

Coyotes are found statewide and can be active day or night, though they are most vocal at dawn and dusk. They prefer forests, swamps, and brushy areas but adapt to suburban habitats as well. Bobcats are harder to spot due to their solitary, elusive nature, but they also occur statewide in forested areas and rocky terrain. Both species are most active during spring and fall. If you hike in state forests or protected areas, you may hear coyotes howling or see fresh tracks in snow or mud. Bobcat sightings are rare, but their presence is confirmed through game cameras and fur that washes up near rivers. Neither predator poses a significant threat to humans.

The nearest established mountain lion populations are in the western United States, particularly the Rocky Mountains, the Sierra Nevada, and the southwestern deserts. The closest confirmed breeding population to Massachusetts is the Florida panther in south-central Florida, which numbers only around 200 individuals and is listed as endangered. Occasional wandering young males from western populations have reached Connecticut and other northeastern states, but they do not establish populations. The distance, lack of prey, and fragmented forests make natural expansion eastward unlikely. If you want to see wild mountain lions, you would need to travel to western states such as Colorado, Utah, or California.

If you travel to the West, learn to recognize mountain lions and understand their behavior. In mountain lion country, hike in groups, make noise, and avoid leaving food or garbage that attracts prey animals. Keep children close and do not approach a mountain lion. If you encounter one, do not run. Instead, face the animal, make yourself appear large, speak firmly, and back away slowly. Most mountain lions avoid humans. Attacks are rare, with fewer than 30 documented attacks and around 15 deaths in North America since 1900. The risk is minimal compared to other hazards of wilderness travel.
