How to Identify Mountain Lion in New Hampshire

Mountain lions are large, solitary wild cats with a tawny or grayish-brown coat, longer at the back of the neck and shoulders. They have a distinctive long, thick tail (nearly as long as their body), small rounded ears, and a small head relative to their muscular frame. Adults typically weigh 90-160 pounds and stand about 24 inches at the shoulder. They have no spots or stripes and cannot roar like African lions; instead, they hiss, growl, purr, and make eerie calls. Their tracks show four toe pads with no claw marks (claws retract like a house cat) and are larger than domestic dog tracks. If you find a track larger than 2.5 inches across in New Hampshire, it is far more likely from a black bear than a mountain lion.

Yes, but bobcats and coyotes are much smaller. Bobcats weigh 15-35 pounds (one-quarter the size of a mountain lion), have tufted ears, a stubby tail, and spotted coats. Coyotes weigh 25-35 pounds, have pointed ears, and appear leaner and more dog-like. Mountain lions are substantially larger and more powerfully built than either animal. If you see a large tawny wild cat in New Hampshire, you are far more likely to be seeing a large wild dog that escaped from captivity, or experiencing a misidentification in low light. True mountain lion sightings in New Hampshire remain unconfirmed.

Mountain lions were hunted to extinction across the Northeast in the 1800s as European colonists and later settlers viewed them as threats to livestock and people. Systematic removal through hunting, trapping, and poisoning eliminated the species from the entire eastern United States by the late 1800s. The wild forests of the Northeast were also cleared for agriculture and development, removing the vast, undisturbed territories that mountain lions require. Unlike other wildlife (black bears, bobcats, deer), mountain lions have not made a comeback in the Northeast because they need hundreds of square miles per individual and are hesitant to establish themselves near developed areas.

Unconfirmed sightings are reported sporadically in New Hampshire and neighboring states, particularly in forested areas along the Connecticut River Valley and western regions bordering Vermont. These rare sightings are believed to be vagrant animals (typically young males) dispersing from western populations, not evidence of an established breeding population. Most reported sightings lack physical evidence and may represent misidentification of large dogs, bobcats seen from a distance, or photographic misidentifications. iNaturalist, the leading citizen science database, shows zero confirmed observations of wild mountain lions in New Hampshire.

Black bears are the largest predator in New Hampshire and are far more common than most people realize. They weigh 200-600 pounds and are frequently seen in populated areas, especially during summer and fall when food is abundant. Coyotes are increasingly common and will boldly approach human settlements. Bobcats are solitary, shy, and rarely encountered, but they do live in most of the state. These three species are the wild predators you may encounter while hiking or living in rural New Hampshire. None of them are aggressive toward humans except under extreme circumstances (mother bears protecting cubs, or a cornered animal).

No. There are no established mountain lion populations in New Hampshire, so mountain lion attacks are not a realistic hiking hazard. You are far more likely to be injured by a fall, a bee sting, or a tick-borne illness than by any wild predator in New Hampshire. Black bears avoid conflict and will typically flee if given the opportunity. Coyotes rarely attack humans. The far greater risk while hiking in New Hampshire is not from large predators but from the environment itself: uneven terrain, weather, and dehydration.

A mountain lion's silhouette is unmistakable if you see one clearly: a long, muscular body with a very long tail and a small head. The tail is the diagnostic feature; it is nearly as long as the body and hangs low when the animal walks. No other wild cat in North America has a tail this long and thick. The body is uniformly colored (no spots or stripes), and the animal moves with a low, slinky gait. In low light or poor visibility, misidentifications are common because the human brain tends to fill in details and impose a 'large predator' interpretation on vague shapes.

Mountain lions still exist in western North America (primarily in the Rocky Mountains, Pacific Northwest, Southwest, and Florida). Western mountain lions are the same species as those that once roamed New Hampshire, but they have never been reestablished in the East. The Florida panther is a critically endangered subspecies (fewer than 200 remain) found only in southern Florida, and it is smaller and lighter-colored than western mountain lions. New Hampshire has no mountain lions; if you want to see one in the wild, you would need to travel to western states such as Colorado, Montana, Wyoming, or Utah.

Yes. New Hampshire law prohibits private ownership of wild mountain lions and other dangerous wildlife. Only licensed zoos, sanctuaries, and research institutions may legally house mountain lions. The ban exists because captive mountain lions are unpredictable, require vast space, pose a significant escape and public safety risk, and suffer in captivity. Mountain lions are solitary, territorial animals that cannot be domesticated and will injure or kill handlers, other animals, and children.
