Identifying Grizzly Bear Scat: A Wildlife Guide

← Camping Essentials & Setup | Essential Tools & Safety

Quick answer

• Grizzly scat is usually large, often over an inch in diameter, and can be found in piles.
• Look for undigested food like berries, hair, and sometimes bones or insect parts.
• Color varies wildly with diet, from dark brown to reddish to even greenish.
• Shape is often log-like or segmented, but can be irregular.
• Location matters: check trails, clearings, and near food sources.
• Always maintain a safe distance and never approach or touch scat.

What to check first (do this before you drive out)

Before you even think about hitting the trail, get your ducks in a row. Knowing what you might encounter is half the battle.

• Land manager / legality: Who’s in charge out there? Is it the Forest Service, BLM, National Park, or state land? Each has its own rules. Make sure you’re allowed to be where you’re going and know any specific regulations for that area. A quick check of their website is usually all it takes.

• Access/road conditions: Can your rig actually get there? Some backcountry roads are no joke. Think about your vehicle – is it 2WD, AWD, or 4×4? What’s the ground clearance? A little mud or snow can turn a fun drive into a tow-truck situation fast. Check recent reports if you can.

• Fire restrictions + weather + wind: This is a big one. Wildfire risk is no joke. Know the current fire restrictions. Check the weather forecast for rain, snow, and especially wind. High winds can make travel dicey and increase the chance of falling trees.

• Water plan + waste plan (Leave No Trace): Where will you get water? Is it potable, or do you need to filter/treat it? And what about trash? Pack it in, pack it out. Always. That includes human waste too – know how to properly dispose of it according to LNT principles. Don’t be that person.

• Safety (wildlife, distance to help, comms): Bears are the main event here, but other critters can ruin your day too. Know what to do if you see wildlife. How far are you from the nearest ranger station or town? Do you have cell service? Consider a satellite communicator for true remote areas.

Step-by-step (field workflow)

Alright, you’re geared up and on the ground. Here’s how to spot grizzly scat without getting too close for comfort.

1. Scan the trail ahead: Look for any unusual piles or deposits on the trail or just off it.

• Good looks like: A clear, distinct pile or log-like deposit.
• Common mistake: Tunnel visioning on your feet. You miss the bigger picture and potential signs. Keep your eyes up.

2. Observe size and shape: Is it big? Is it clumpy or segmented?

• Good looks like: A pile at least an inch or two thick, often longer. May look like a segmented log.
• Common mistake: Mistaking small animal droppings for bear scat. Grizzly sign is usually substantial.

3. Note the color: What shade is it? Dark brown, black, reddish, or even greenish?

• Good looks like: Color that varies depending on what the bear ate. Berries can make it reddish or purplish.
• Common mistake: Assuming a specific color means something specific. Diet is the biggest factor.

4. Look for undigested material: This is the smoking gun. What’s sticking out?

• Good looks like: Visible bits of berries, seeds, grass, hair, insect exoskeletons, or even small bone fragments.
• Common mistake: Getting too close to examine details. Use binoculars or a telephoto lens.

5. Identify the location: Where did you find it?

• Good looks like: Near berry patches, meadows, game trails, or along water sources.
• Common mistake: Ignoring context. Scat found in a highly trafficked human area might be from a different animal or even intentional.

6. Smell (from a distance!): Does it have a pungent, musky odor?

• Good looks like: A strong, noticeable smell, especially on a warm day.
• Common mistake: Getting close enough to smell it. Use the wind to your advantage.

7. Check for associated signs: Are there tracks, claw marks on trees, or disturbed vegetation nearby?

• Good looks like: Clear tracks or other evidence that confirms bear activity.
• Common mistake: Focusing solely on the scat and missing other, potentially more definitive, signs.

8. Document (safely!): If you want to remember it, take photos from a safe distance.

• Good looks like: Clear photos showing scale and contents without getting near the deposit.
• Common mistake: Trying to collect a sample or get a selfie with the scat. Seriously, don’t.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Getting too close to examine scat	Increased risk of surprising a bear, potential attack.	Use binoculars or zoom lenses. Maintain a safe distance.
Touching or collecting scat	Spreading parasites or diseases, potential DNA contamination.	Never touch it. If you must document, use photos.
Mistaking scat for something else	False alarm, or worse, underestimating bear presence.	Learn the key characteristics of grizzly scat.
Ignoring scat location	Misinterpreting animal activity, missing important habitat clues.	Always consider where you found the scat.
Relying solely on scat for ID	Missing other critical bear signs like tracks or rubs.	Look for a combination of signs.
Assuming scat is fresh	Misjudging how recently a bear was in the area.	Look for signs of freshness (moisture, intact shape). Older scat dries out and crumbles.
Not making noise while hiking	Surprising a bear, increasing the chance of a defensive encounter.	Talk, sing, or clap your hands periodically, especially in areas with limited visibility.
Panicking when scat is found	Poor decision-making, potentially leading to a dangerous situation.	Stay calm, assess the situation, and back away slowly.
Not knowing local bear activity reports	Being unaware of recent bear sightings or problem areas.	Check with local land managers or park rangers before heading out.
Failing to properly store food	Attracting bears to your campsite, leading to habituation and conflict.	Use bear-resistant canisters or hang food properly. Never leave food unattended.

Decision rules (simple if/then)

• If you see a large, segmented pile of droppings with visible undigested food, then it’s likely grizzly bear scat because this matches the typical characteristics.
• If the scat is small and uniform, then it’s probably not grizzly bear scat; it could be from a coyote, fox, or even a large bird.
• If the scat is found in a berry patch during berry season, then it’s a strong indicator of grizzly bear activity because berries are a primary food source.
• If you find scat right on a well-maintained hiking trail, then be extra cautious because bears often use trails, and you might be entering their travel corridor.
• If the scat appears very old, dried out, and crumbly, then a bear was in the area, but not necessarily recently.
• If you find scat and hear rustling in nearby bushes, then slowly back away without making sudden movements because you might be close to the bear that left it.
• If you are unsure if it’s grizzly scat, then err on the side of caution and assume it is, maintaining a safe distance.
• If you are hiking in grizzly country and see scat, then make noise to alert any bears that might be nearby and want to avoid you.
• If the scat has a strong, pungent odor, then it’s likely fresh, meaning a bear was in the vicinity relatively recently.
• If you find scat and are alone, then consider turning back or taking a different route because solo encounters can be more dangerous.
• If you plan to camp in an area with signs of bear activity, then ensure your food storage is impeccable because attracting bears to your camp is a recipe for disaster.

FAQ

What’s the biggest difference between grizzly and black bear scat?

Grizzly scat tends to be larger, often over an inch in diameter, and contains more varied undigested material like hair and bone fragments due to their omnivorous diet. Black bear scat is usually smaller and more often composed of berries, insects, and vegetation.

How do I know if the scat is fresh?

Fresh scat is usually moist, dark, and holds its shape. Older scat will be drier, lighter in color, and may start to crumble or be covered by insects.

Can I tell what a grizzly ate just by looking at its scat?

Often, yes. You’ll see recognizable bits of berries, seeds, grass, insects, or even fur and bone. The color can also give clues; for example, a diet heavy in berries might make the scat reddish or purplish.

What if I find scat near my campsite?

This is a sign that bears are frequenting the area. You need to be extra vigilant about food storage, making noise, and keeping your campsite clean. If it looks fresh, you might consider moving your camp if possible and safe.

Is it safe to get close enough to smell the scat?

No, it’s never a good idea to get close enough to smell scat. You risk surprising a bear or getting too close to potential contaminants. Use the wind to your advantage to catch any odor from a safe distance.

What should I do if I see grizzly scat on a trail I’m hiking?

Stop, stay calm, and slowly back away the way you came. Make noise as you retreat to let any nearby bears know you’re there. Do not try to get closer for photos or to examine it.

Can scat help me identify a specific bear?

While you can’t identify an individual bear from scat alone, wildlife biologists can sometimes collect DNA samples from hair or other material within the scat to learn about the bear’s genetics, diet, and population health.

What if the scat is just a pile of grass?

A pile of grass could be from a grizzly, especially if it’s large and deposited in a grassy meadow. However, it could also be from other herbivores. Look for other clues to confirm if it’s grizzly sign.
