How to Tell a Mountain Lion from a Bobcat or Lynx

Updated 6 November 2026 · Standard formula, shown below

This guide helps you quickly and confidently identify a mountain lion (cougar/puma) versus a bobcat or lynx when you spot a wild cat in North America. You’ll learn the key differences in size, tail length, ear tufts, and coat patterns, plus what to do if you’re unsure. No special equipment is needed—just your eyes and a little patience.

What You’ll Need

A clear view of the animal (binoculars help, but aren’t required)
A safe distance—never approach any wild cat
Your phone or camera to take a photo if possible (for later ID and reporting)
Knowledge of your region (which species are present)

Step-by-Step

Check the tail first. This is the most reliable single feature. A mountain lion has a long, thick tail that is about one-third of its total body length—often dragging or curling. Bobcats and lynx have very short, stubby tails (4–7 inches) that look like they’ve been docked. If you see a long tail, it’s a mountain lion; if the tail is barely visible, it’s a bobcat or lynx.
Estimate the overall size. Mountain lions are much larger: adults weigh 80–200 pounds and stand about 2–3 feet at the shoulder. Bobcats are smaller (15–40 pounds) and lynx are similar (20–45 pounds). If the cat is roughly the size of a large dog, it’s likely a mountain lion. If it’s closer to a medium-sized dog or a big house cat, it’s a bobcat or lynx.
Look at the ears. Lynx have prominent black ear tufts (long, dark hairs on the tips of their ears) and black-tipped tails. Bobcats also have ear tufts, but they are smaller and less conspicuous. Mountain lions have rounded, tuftless ears—no black tufts at all.
Examine the coat pattern. Mountain lions have a solid, tawny (tan/brown) coat with no spots or stripes as adults (kittens have spots that fade). Bobcats have a spotted and barred coat with a reddish-brown base and dark spots and streaks. Lynx have a more uniform grayish-brown coat with faint spots and a lighter belly.
Check the face and ruff. Lynx have a distinctive, wide face with a prominent black-tipped ruff (long hair around the cheeks) and a black-tipped tail. Bobcats have a shorter ruff and a more pointed face. Mountain lions have a smooth, unmarked face with a distinct white muzzle and white patches around the eyes.
Observe the legs and paws. Lynx have very large, furry paws that act like snowshoes, and their legs look relatively long for their body. Bobcats have smaller paws and shorter legs. Mountain lions have large, but not disproportionately furry, paws and long, powerful legs.
Consider the habitat and region. Mountain lions are found throughout western North America, from Canada to South America, and have been expanding eastward. Bobcats are widespread across the US and southern Canada, in a variety of habitats. Lynx are primarily found in northern boreal forests (Canada, Alaska, and northern US states like Maine, Minnesota, and Washington). If you’re in the deep south or desert, it’s almost certainly not a lynx.
Watch the behavior. Mountain lions are secretive and usually avoid humans, often climbing trees or moving away quickly. Bobcats and lynx are also shy but may be more likely to freeze or slink away. If the cat is climbing a tree, a mountain lion is more likely to do so to escape, but bobcats also climb trees, so this is not definitive.

Common Mistakes

Relying on size alone: A young mountain lion can be similar in size to a large bobcat. Always check the tail—size can be misleading.
Ignoring the tail: Some people mistake a bobcat’s short tail for a long tail if it’s raised or if the animal is moving. Wait for a clear side view.
Confusing a lynx with a bobcat: Both have short tails and tufted ears, but lynx have larger paws, longer ear tufts, and a more uniform gray coat, while bobcats have spots and a reddish tone.
Thinking a mountain lion has spots: Adult mountain lions are solid-colored. Only kittens have spots, which fade by about 6 months of age.
Assuming all wild cats are mountain lions: In many areas, bobcats are far more common. Don’t jump to conclusions based on excitement or fear.

Tips

Use binoculars or a zoom lens to get a closer look without approaching.
Take a photo or video if you can—this helps with later identification and is useful for wildlife authorities.
Note the location, time, and behavior to help with ID and reporting.
If you see tracks, look for the shape: mountain lion tracks are large (3–4 inches) with no claw marks (retractable claws), while bobcat tracks are smaller (1.5–2 inches) and also lack claw marks. Lynx tracks are large and furry, with a snowshoe-like appearance.
Check for a black-tipped tail: both bobcats and lynx have black on the top of the tail, but lynx have a fully black tip all around, while bobcats have a black top and white underside.

Troubleshooting

What if you only caught a glimpse? If the animal ran off, focus on the tail length and overall color. A long, tawny tail means mountain lion; a short, spotted tail means bobcat/lynx.

What if the animal is far away? Use binoculars or a spotting scope. If you can’t see the tail or ears, try to estimate the size relative to nearby objects (e.g., a fence post, tree trunk).

What if you see a cat at dusk or dawn? Poor light can hide colors and spots. Look for the silhouette: a mountain lion has a long, low profile with a long tail; bobcats/lynx have a more compact, rounder body with a short tail.

What if you’re in an area where both mountain lions and bobcats live? Use the tail as the deciding factor. If the tail is long, it’s a mountain lion; if short, it’s a bobcat (or lynx, if in northern forests).

What if the cat is in a tree? Both bobcats and mountain lions climb trees. Check the tail and ear tufts—if you see a long tail, it’s a mountain lion; if short tail and tufted ears, it’s a bobcat or lynx.

Frequently Asked Questions

Q: Can a bobcat be as big as a mountain lion?
A: No. Adult mountain lions are 2–3 times larger than bobcats. A bobcat rarely exceeds 40 pounds, while mountain lions start at 80 pounds.

Q: Do mountain lions have tufted ears like lynx?
A: No. Mountain lions have rounded, tuftless ears. Lynx and bobcats have black ear tufts, though bobcat tufts are smaller.

Q: What is the easiest way to tell a bobcat from a lynx?
A: Look at the tail and paws. Lynx have a completely black-tipped tail and huge, furry paws; bobcats have a black top on the tail with a white underside, and smaller paws.

Q: Are mountain lions ever spotted?
A: Only as kittens. Adult mountain lions have a solid, tawny coat. If you see spots on a large cat, it’s a bobcat or a young mountain lion (but the tail will be short if it’s a bobcat).

Q: What should I do if I see a wild cat?
A: Stay calm, do not run, and back away slowly while facing the animal. Give it space to escape. If it approaches, make yourself look larger, make noise, and throw objects if necessary. Report the sighting to local wildlife authorities.

Q: Are lynx only found in Canada?
A: Lynx are found in Canada and Alaska, but also in the northern United States (e.g., Maine, Minnesota, Montana, Washington). They prefer boreal forests.
