Grizzly Bear Hibernation: The Process
Grizzly bears hibernate 4-7 months, dropping heart rate to 8-19 bpm while females give birth mid-sleep. The physiology, the den, and climate disruption.
Grizzly Bear Cubs and Family Dynamics: An In-Depth Look
Grizzly cubs weigh 400-500 g at birth inside a winter den. The first 3 years of life, the mother-cub bond, and why male infanticide shapes family survival.

Romania holds 6,000+ brown bears, Europe's largest population. Full breakdown of brown bear range across 22 European countries with current numbers and trends.
Brown Bear vs Grizzly Bear: Same Species, Different Name
Every grizzly IS a brown bear, but not every brown bear is a grizzly. Untangling the taxonomy, regional names, and why coastal bears are bigger than inland.
Brown Bear Subspecies: 16 Distinct Types
Every brown bear on Earth is Ursus arctos, but subspecies range from 750 kg Kodiaks to 30 surviving Gobi bears. The full taxonomy, minus the obsolete names.

Brown bear cubs weigh 350-500 g at birth mid-hibernation. The mother-cub bond, infanticide risk from boars, and how maternal care shapes survival.
Do Pandas Belong to the Bear Family? Taxonomy
Yes, giant pandas are bears. The 100-year debate ended with DNA evidence placing them firmly in Ursidae. Red pandas however are a different family altogether.

Sun bears inhabit lowland tropical forest across 11 SE Asian countries from Bangladesh to Borneo. Range, populations, and the deforestation pressure.
Spectacled Bear Range: Habitat Across Six Countries
Spectacled bears (Andean bears) live in cloud forests across six countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, and far northern Argentina.

Sun Bear Tongue: A Unique Tool for Feeding
Sun bears have the longest tongue of any bear, 20-25 cm, evolved for honey raids and termite mounds. The mechanics, the meals, and how it shapes the species.
Sun Bears: Cubs, Mothers, and Their Unique Bond
Sun bear cubs are born at 250-325 g in tree hollow dens. The reproduction cycle, the 18-month maternal bond, and the orphan-cub pet-trade crisis.
