- Banff National Park is home to 53 species of mammals.
- Grizzly bears are more plentiful than black bears in Banff National Park. At present, it is estimated that approximately 80 grizzly bears and 60 black bears reside in the park.
- In Banff National Park, there are currently 41 wildlife crossing structures (6 overpasses and 35 underpasses) that help wildlife safely cross the busy Trans-Canada Highway. Since monitoring began in 1996, 11 species of large mammals—including bears, elk and cougar—have used crossing structures more than 200,000 times.
- Most of the backcountry wilderness in the park is subalpine forest, alpine tundra or rock and ice, and is thus more suited to grizzlies than blacks. However, visitors are more likely to see black bears because they frequent the low-lying valleys through which our park roads run.
- Park grizzlies are currently part of a comprehensive grizzly bear study in the Central Rockies Ecosystem. Over twenty silvertips have been radio collared and are being monitored weekly using telemetry technology.
- Cougar, lynx, wolverine, weasels, northern river otter and wolves are the primary predatory mammals. Elk, mule deer, and white-tailed deer are common in the valleys of the park, including around (and sometimes in) the Banff townsite, while moose tend to be more elusive, sticking primarily to wetland areas and near streams. In the alpine regions, mountain goats, bighorn sheep, marmots and pika are widespread. Other mammals such as beavers, porcupines, squirrels, chipmunks, and Columbian ground squirrels are the more commonly observed smaller mammals.
- Following their extinction from the park, elk were reintroduced from Yellowstone in the 1920s. Approximately 1000 elk roam the park today.
- Due to the harsh winters, the park has few reptiles and amphibians with only one species of toad, three species of frog, one salamander species and two species of snakes that have been identified.
- At least 280 species of birds can be found in Banff including many predatory species such as bald and golden eagles, red-tailed hawk, osprey, and merlin.
- Endangered species in Banff include the Banff Springs snail (Physella johnsoni) which is found in the hot springs of Banff. Woodland caribou are listed as a threatened species.
