Big Bear Lake, nestled within the San Bernardino Mountains, supports a diverse array of animal life. This alpine environment, with elevations from 6,750 to 9,000 feet, provides varied habitats for numerous species. Distinct seasons, from snowy winters to warm summers, contribute to the rich biodiversity around this Southern California destination.
Mammals of Big Bear
The Big Bear region is home to several mammal species. Black bears, though present, are rarely seen by visitors. These omnivores often climb trees when perceiving danger and can remain in their dens for several months during winter.
Coyotes are abundant, often active during dusk and dawn. They primarily prey on smaller animals like squirrels and rabbits but may pose a risk to unattended pets. Mule deer, identifiable by their large ears and grayish-brown coats, are also found, though sightings can be infrequent, especially along mountain roads at night.
Smaller mammals like squirrels, chipmunks, and raccoons are frequently observed. Less commonly seen mammals include bobcats and reclusive mountain lions. Grey foxes, distinguished by their bushy tails and salt-and-pepper colored fur, also inhabit the mountainous terrain.
Birds and Reptiles
Big Bear Lake and its surrounding areas host a wide variety of avian species, including over 250 types of birds. Raptors such as bald eagles are present, particularly during winter from November to April, observed hunting near the lake. Other birds of prey include hawks, owls, and falcons, frequently seen soaring above the landscape.
The region’s birdlife includes numerous songbirds, such as jays, woodpeckers, and various finches. Waterfowl are abundant on Big Bear Lake, with species like ducks (including mallards and ruddy ducks), coots, and Canada geese. Shorebirds, terns, and white pelicans also frequent the lake’s shores.
Reptiles are present in the Big Bear ecosystem, though they can be less conspicuous than birds or mammals. Common species include various lizards, such as the western fence lizard and southern alligator lizard. Several snake species inhabit the area, with the Southern Rubber Boa being a non-venomous type found in Big Bear’s cool forests. While many snakes are harmless, the western rattlesnake is also present in the region, necessitating caution.
Fish, Amphibians, and Safe Encounters
Big Bear Lake supports a thriving aquatic ecosystem. Rainbow trout are the most popular fish species and are regularly stocked, thriving in the lake’s deeper, cooler waters even during warmer months. The lake also contains largemouth and smallmouth bass, particularly active from spring through summer. Other fish species include bluegill, crappie, pumpkinseed, and channel catfish.
Amphibians are also part of Big Bear’s wildlife, with species like the western toad, and various frogs and salamanders inhabiting the waterways and surrounding moist environments. These creatures often begin their lives in water with gills before developing the ability to live on land. Amphibians are sensitive to environmental changes, indicating the health of their ecosystem.
Interacting with Big Bear’s wildlife requires responsible practices to ensure both human and animal safety. Maintaining a respectful distance from all animals, and feeding wild animals is discouraged as it can alter their natural behaviors and lead to dependence or aggression. Securing food and trash, especially in camping areas, prevents animals like bears and raccoons from becoming habituated to human food sources. If an encounter with a larger animal occurs, remaining calm, making noise, and slowly backing away can help de-escalate the situation.
