As the ice melts and the seals gain the advantage, polar bears tend fast through most of the summer. Sometimes they will try and hunt seal at night or scavenge for birds, but rarely are there high calory meals. This means that polar bears prefer to rest during the summer months and exert minimal energy.
Can a polar bear kill a seal?
They mainly eat ringed seals, but may also eat bearded seals. Polar bears hunt seals by waiting for them to come to the surface of sea ice to breathe.

Where do polar bears stay in summer?
Polar bears in warmer climates may become stranded on land. In summer, sea ice melts along the coastlines, and pack ice (floating sea ice, or floes, not connected to land) moves so far north, that polar bears can’t reach it, even though they are excellent swimmers.
Where do polar bears live in summer?
Some polar bears stay on permanently frozen sea ice in the Arctic Basin, but most live on the annual sea ice that forms around the Arctic Basin. This annual sea ice melts in the summer, so polar bears are forced to spend several months on land while they wait for it to freeze over again, according to the IUCN.
Why are polar bears only in the North Pole?
The closest land to the North Pole is over 800km (497 mi) away! The sea ice is the polar bear’s habitat. This frozen crust on the surface of the polar sea is always moving, and so are polar bears. … As sea ice cover and distribution changes over time, so do the areas polar bears can access.
What eats a polar bear?
