Banff National Park, Bow Valley

The moose (Alces alces) is the largest member of the deer family in North America. In Banff National Park, moose favour wetlands, riparian corridors, and willow thickets; habitat that limits their distribution but makes them iconic where they occur.

Identification: Dark brown to black; long legs; distinctive drooping snout (“bell” under chin); palmate (flat, shovel-shaped) antlers on bulls. Cows lack antlers. Much larger than elk or deer; adult bulls can exceed 1,800 lb (800 kg). Calves born May–June.

Habitat and diet: Moose require wetlands, lakeshores, and willow-dominated riparian zones. Browse on willow, aspen, aquatic plants, and forbs. In winter, concentrate in lower elevations with accessible forage.

Behaviour: Generally solitary; cows with calves may be aggressive. Bulls in rut (September–October) can be unpredictable. Moose are strong swimmers and often wade in lakes and ponds.

Viewing: Prime locations include Vermilion Lakes, the Bow Valley near Banff, Johnston Canyon, and the Icefields Parkway. Dawn and dusk are best. Maintain at least 30 m distance; moose charge more often than bears in the park. Never approach cows with calves.
