Need to know

• The moose is the largest living member of the deer family (Cervidae).
• A mature adult bull moose can weigh up to 820 kg and stand over 2 m at the shoulder.
• Moose are excellent swimmers and can swim several kilometers at a time, even submerging to feed on aquatic plants.

About the Moose

The moose (Alces alces) is an iconic and majestic mammal native to the northern forests of North America, Europe, and Asia. As the largest extant member of the deer family, moose are famous for their towering stature, massive antlers on males, and solitary nature. They play a vital ecological role in maintaining northern ecosystem health by feeding on a wide range of plants and influencing vegetation structure.

Moose are highly adapted to cold climates and can thrive in areas with deep snow. They are frequently seen near lakes, rivers, and wetlands, where they forage on aquatic plants and shrubs. These animals are generally solitary except during the breeding season, when males compete for females. Ongoing research is expanding our understanding of their behavior, migration, and adaptation to climate change.

Physical characteristics

Size: 2.4–3.1 m in length; males stand 1.4–2.1 m at the shoulder. Weight: Adults weigh 360–820 kg (males largest). Lifespan: Average 15 years in the wild, up to 27 years.

• Massive palmate antlers (males only)
• Long, flexible snout and upper lip
• Large dewlap ('bell') hanging from the throat
• Long legs adapted for wading and deep snow
• Short tail and large, elongated head

Habitat and range

Original range: Northern forests across Eurasia and North America, primarily boreal and temperate woodland zones

Current distribution: Widespread across Canada, Alaska, northern United States, Scandinavia, the Baltic States, Russia, Eastern Europe, and northern Mongolia

Preferred environments: Boreal and mixed forests, Wetlands and swamps, Riverine woodlands, Lake margins

Regions: Alaska, Canada, New England, Scandinavia, Baltic States, Russia (including Siberia), Northern Mongolia, Poland

Where to see Moose

• Denali National Park, Alaska — June–August. Look for moose at dawn or dusk near wetlands and riverbanks.
• Swedish Lapland — May–September. Best spotted in early morning or evening in forest clearings and lakeshores.
• Algonquin Provincial Park, Ontario — May–June. Watch for moose feeding on aquatic plants along the edges of lakes and marshes.

Behavior and diet

Diet: Herbivorous: feeds on leaves, twigs, bark of willow, birch, and aspen, as well as aquatic plants such as water lilies and horsetails.

Social structure: Primarily solitary except during mating season (rut) and mothers with calves; bulls may gather temporarily to compete for mates.

Communication: Communicate through vocalizations (grunts, bellows during rut), body language, and scent marking (especially during breeding season).

• Excellent swimmer, often seen wading or diving for aquatic vegetation
• Solitary except during rut and calving
• Uses antlers for dominance displays and combat during breeding
• Calves can stand and walk within hours of birth

Interactions with other animals

• Wolf (predator): Wolves prey on moose, particularly calves, sick, or old individuals.
• Bear (Brown and Black) (predator): Bears may hunt moose calves or vulnerable adults, especially during spring.
• Beaver (symbiotic/indirect): Beaver activity creates wetland habitats that benefit moose for foraging.

Conservation

IUCN Red List status: Least Concern

Threats

• Habitat loss due to deforestation and human encroachment
• Climate change affecting snow depth and food resources
• Increased predation (wolves and bears) in some regions
• Parasites (notably winter ticks) and disease
• Vehicle collisions

Conservation efforts

• Habitat preservation and wetland restoration
• Research and monitoring of population dynamics
• Regulated hunting for sustainable populations
• Mitigation of road and rail animal collisions

How to help

• Support conservation organizations working to preserve forests and wetlands
• Drive carefully in moose habitats, especially at dawn and dusk
• Advocate for wildlife corridors and road crossing structures
• Report moose sightings to local wildlife monitoring programs

Moose facts for kids

Moose are huge mammals that live in northern forests. They have big, flat antlers (only the boys grow them), long legs, and love to eat plants in the water. Moose are mostly on their own except when baby moose are with their moms.

• Moose are so tall that many adults can look into the window of a second-story house!
• A moose's antlers can grow as wide as a car is long.
• Baby moose are called calves and can run faster than a human only days after birth.
• Moose can hold their breath and dive underwater to eat plants at the bottom of lakes.
• They have long noses to help them grab branches and eat underwater.

Did you know? Did you know moose can swim for several miles without stopping, and they even eat underwater? They're like giant, furry scuba divers!
