Mendocino National Forest is home to a diverse array of mammals. Some of the most prominent species you may encounter include:

Black Bears

These majestic creatures are the largest predators in the forest. Although they are not typically aggressive, it’s essential to maintain a safe distance and store food properly to avoid attracting them to your campsite.

Los Padres National Forest black bear

Black bears are commonly found in wooded areas with dense vegetation and near streams or rivers. They may also be seen near campgrounds, such as Atchison Campground and Pogie Point Campground, in search of food.

Black bears are omnivorous and primarily solitary, except for mothers with cubs. They typically forage in the early morning and late evening, consuming berries, nuts, insects, and occasionally small mammals or carrion. 

Mountain Lions

Also known as cougars, these elusive cats inhabit the forest’s more remote areas. They generally avoid humans but can be dangerous if they feel threatened.

Mountain lions inhabit the more remote and rugged areas of the forest, often at higher elevations. They have been reported in the vicinity of Lake Pillsbury and Snow Mountain Wilderness.

Mule Deer Great Basin National Park

Mule deer are found throughout the forest, with higher concentrations in areas with abundant food sources, such as the Grindstone Ranger District and Upper Lake Ranger District.

Mule deer are herbivorous and crepuscular, feeding on a variety of vegetation, including shrubs, grasses, and forbs. They may form large herds during the winter months and can be seen grazing near meadows and clearings.

Gray Foxes

Smaller than their red counterparts, gray foxes are known for their ability to climb trees. They are primarily nocturnal and feed on a variety of small mammals, insects, and fruits.

gray fox Saguaro National Park

Gray foxes can be found in a range of habitats, from dense forests to open grasslands. They have been spotted around campgrounds like Lake Red Bluff Recreation Area and Hammerhorn Campground.

Gray foxes are omnivorous, feeding on small mammals, insects, and fruit. They are mainly nocturnal and known for their ability to climb trees to escape predators or search for food.

North American River Otters

Often found near rivers and lakes, these playful mammals are excellent swimmers and can often be seen frolicking in the water.

River otters are frequently found near water sources, such as Eel River, Stony Creek, and Lake Pillsbury.

River otters Ocala National Forest

These playful mammals are social, forming family groups that hunt and play together. They feed primarily on fish, amphibians, and crustaceans and are often seen sliding on muddy banks or playing in the water.

Roosevelt Elk

Roosevelt elk, the largest subspecies of North American elk, can be found in various habitats throughout Mendocino National Forest, including meadows, grasslands, and mixed conifer forests. 

They are particularly abundant in the northern sections of the forest, such as the Yolla Bolly-Middle Eel Wilderness and Covelo Ranger District.

Theodore Roosevelt National Park ELK

These large herbivores feed on a variety of grasses, forbs, and woody plants.

During the rutting season, which typically occurs from late August to early October, dominant male elk (bulls) engage in intense battles with rival bulls to establish dominance and secure mating rights. 

This period is marked by the distinctive bugling calls of the males, which can be heard echoing through the forest.

Female elk (cows) give birth to a single calf, usually between late May and early June. The calves are born with spots that help camouflage them in the underbrush. 

The mother is highly protective during this period, and it is essential to give elk plenty of space to avoid causing distress or inadvertently provoking an attack.

To increase your chances of spotting elk, plan your visit during the early morning or late evening hours when they are most active. Look for meadows, clearings, or other open areas where elk may come to feed. 


The Mendocino National Forest is a haven for birdwatchers, with over 200 species recorded. Some highlights include:

Bald Eagles

These impressive raptors can be spotted soaring high above the forest, primarily around bodies of water where they hunt for fish.

Bald eagles are often seen near water sources, such as Lake Pillsbury, Eel River, and Stony Creek.

Northern spotted owls are found in old-growth forests, particularly in the Snow Mountain Wilderness and Yolla Bolly-Middle Eel Wilderness.

Northern Pygmy Owl Yosemite

These nocturnal birds are territorial and typically remain in the same area throughout their lives. They feed on a variety of small mammals, including rodents and other small birds.

Pileated Woodpeckers

With their striking red crests, these large woodpeckers are hard to miss as they excavate cavities in dead trees to search for insects.

Pileated woodpeckers inhabit mature forests with an abundance of dead trees, such as those found in the Grindstone Ranger District and Upper Lake Ranger District.

Pileated woodpeckers Deschutes National Forest

These large, striking birds create distinctive rectangular holes in dead trees as they search for insects, particularly carpenter ants and wood-boring beetles.

These small, colorful birds are a treat to observe as they flit about in search of insects and berries.

Western bluebirds can be found in open woodlands, meadows, and around campgrounds like Fouts Springs Campground and Oak Flat Campground.

Western Bluebirds

These small, colorful birds are insectivorous, feeding on a variety of insects, as well as berries and fruits. They are often seen perched on low branches or fences, swooping down to catch insects in flight.

Blue Grouse (Sooty Grouse)

Blue grouse, also known as sooty grouse, can be found in coniferous forests throughout Mendocino National Forest. 

They are more commonly seen at higher elevations, such as the Snow Mountain Wilderness and the Yolla Bolly-Middle Eel Wilderness.

Blue Grouse

Blue grouse are primarily ground-dwelling birds but can also be found perching in trees. They are generally solitary, except during the breeding season. These birds are omnivorous, feeding on a variety of leaves, buds, fruits, and insects.

The mating season for blue grouse occurs during the spring, usually between April and June. 

During this period, male grouse perform elaborate displays, including fanning their tails, puffing out their chests, and producing deep, resonant hooting calls to attract females. 

These displays often take place on traditional “lek” sites, where multiple males gather to compete for mates.

While hiking through coniferous forests, keep an eye out for the birds on the ground or perched in trees. Use binoculars or a camera with a zoom lens to observe them from a distance without disturbing their natural behavior.

Reptiles and Amphibians

Mendocino National Forest’s ecosystems also support an array of reptiles and amphibians. Some examples include:

Western Pond Turtles

Found near lakes and ponds, these turtles are the only native freshwater turtle species in California.

Western Pond Turtles

Western pond turtles can be found in and around water sources, such as Lake Pillsbury, Eel River, and Stony Creek.

These turtles are diurnal, spending much of their day basking in the sun on logs or rocks near the water’s edge. They are omnivorous, feeding on aquatic plants, insects, and small fish.

Northern Pacific Rattlesnakes

Although these venomous snakes are a rare sight, it’s essential to be cautious when hiking, as they are known to inhabit the region.
