Which term best describes the diet of grizzly bears?
Herbivore
Omnivore
Carnivore
Detritivore
Grizzly bears consume a wide variety of foods including plants, insects, and other animals. Because they eat both vegetation and meat, their diet is classified as omnivorous. This dietary flexibility helps them survive in different seasons and habitats. National Geographic
To which family do grizzly bears belong?
Ursidae
Felidae
Canidae
Mustelidae
Grizzly bears are part of the family Ursidae, which includes all bear species. Members of Ursidae share traits like plantigrade feet and a short tail. This family distinction places them alongside polar bears, black bears, and other brown bears. Britannica
In which continent are grizzly bears naturally found today?
Asia
North America
Africa
Europe
Grizzly bears are naturally found in North America, ranging from Alaska through western Canada and into parts of the northwestern United States. Historical ranges in Europe and Asia have largely vanished, leaving North America as their primary habitat. Conservation efforts focus on maintaining their populations in this region. National Park Service
What physical feature gives grizzly bears their name?
Silver-tipped hairs
Sharp claws
Large canines
Hump on their shoulders
The term grizzly comes from the silver-tipped hairs that give the bears coat a 'grizzled' appearance. These lighter tips on darker fur are especially noticeable in sunlight. The distinctive hair pattern is what inspired their common name. National Geographic
How long is the typical hibernation period for grizzly bears?
79 months
57 months
24 months
35 months
Grizzly bears in colder regions hibernate for approximately five to seven months each year. The exact duration depends on food availability and climate. During this time, they can drop their heart rate and do not eat or drink until spring. National Geographic
What is the average weight range of an adult male grizzly bear?
500700 lbs (227318 kg)
300500 lbs (136227 kg)
700900 lbs (318408 kg)
200300 lbs (90136 kg)
Adult male grizzly bears typically weigh between 300 and 500 pounds, though some individuals can be larger in prime habitats. Their weight varies by season, increasing before hibernation as they store fat. Understanding weight ranges helps in studying their health and reproductive success. Wikipedia
At what age do grizzly bear cubs usually become independent from their mother?
6 months
1 year
3 years
2 years
Grizzly bear cubs typically stay with their mother for about two years before setting off on their own. This period allows them to learn crucial survival skills like foraging and predator avoidance. After independence, they establish their own territories. National Park Service
What type of habitat do grizzly bears prefer?
Coastal marshes
Alpine meadows and forests
Desert valleys
Urban parks
Grizzly bears thrive in alpine meadows, forest edges, and river valleys where food sources like berries and salmon are abundant. These diverse habitats offer both cover and foraging opportunities. They avoid heavily urbanized or purely desert areas. National Geographic
Grizzly bears have a bite force estimated at about how many pounds per square inch (psi)?
800 psi
1500 psi
1200 psi
2000 psi
Studies estimate that grizzly bears can exert around 1,200 psi of bite force, one of the strongest among terrestrial carnivores. This powerful bite helps them crush bones and tough vegetation. Their jaw muscles are exceptionally well developed. Sciencing
During salmon spawning season, what percentage of a grizzly bear's diet can salmon represent?
510%
1520%
3040%
5060%
In coastal regions, salmon runs can make up 5060% of a grizzly bear's diet during peak spawning season. The high protein and fat content help bears fatten up for hibernation. Loss of salmon habitat can therefore heavily impact bear populations. National Park Service
Which of the following diseases is known to affect grizzly bear populations?
Brucellosis
Canine distemper
Chronic wasting disease
Avian influenza
Brucellosis is a bacterial infection that can be transmitted to grizzly bears through infected ungulate carcasses. While not all populations are affected, outbreaks can influence bear health and reproduction. Monitoring helps wildlife managers track disease spread. CDC
Genetic studies suggest modern North American grizzly bears diverged from Old World brown bears approximately how many years ago?
20,000 years
100,000 years
1 million years
400,000 years
Molecular analyses indicate that North American brown bears (grizzlies) diverged from Eurasian brown bear lineages roughly 20,000 years ago, following the last glacial maximum. This split led to distinct genetic adaptations in both populations. Further details are explored in genetic research publications. ScienceDaily

Cheat Sheet

  1. Habitat Diversity -

    Grizzly bears occupy three primary habitats - boreal forests, lowland meadows, and riverine corridors - often remembered with the mnemonic "BLR." According to the National Park Service, these habitat zones influence diet selection, mating behavior, and human encounter rates. Mapping these areas boosts your ability to predict bear movements during peak foraging seasons.

  2. Hibernation Physiology -

    During hibernation, grizzlies reduce their metabolic rate by up to 50%, relying on stored fat reserves for energy (USGS). Their body temperature drops only a few degrees, allowing quick arousal if disturbed, a concept known as shallow torpor. Remember "Fat First" to recall that lipid metabolism fuels them for 5 - 7 months underground.

  3. Omnivorous Diet & Foraging -

    Grizzly bears are classic opportunistic omnivores, consuming everything from salmon and small mammals to berries and roots (Journal of Wildlife Management). Peak berry season can provide up to 90% of their daily calories - sometimes over 20,000 kcal per day! Use the phrase "Fish, Fruit, Forage" to recall their top three food sources.

  4. Maternal Behavior & Cub Development -

    Female grizzlies typically rear cubs for 2 - 3 years, teaching them survival skills like digging for roots and fish-catching (Wildlife Conservation Society). Cubs weigh just 0.5 kg at birth and double their weight every month in the den, thanks to rich mother's milk. The "2/3 Rule" helps you remember that cubs stay with mom for roughly two years before splitting off.

  5. Seasonal Movements & Conservation Status -

    Grizzlies exhibit seasonal home ranges that can span 200 - 1,500 km², varying by sex and resource availability (Canadian Journal of Zoology). Populations in the Lower 48 are listed as Threatened, while Canada and Alaska report stable or increasing numbers. Keep "RANGE" in mind - Reproduction, Access, Nutrition, Geography, Endangered - to link movement ecology with conservation priorities.
