How do polar bears get food in the tundra?

Polar bears primarily hunt seals, which are their main source of food in the tundra. They use a technique called still-hunting, where they wait by breathing holes in the ice for seals to surface for air. Additionally, they may utilize their sense of smell to locate seals beneath the snow or ice. During summer months, when ice melts, they may also scavenge on carcasses or hunt birds and eggs if necessary.
