How do polar bears capture their prey?

How do polar bears capture their prey?

They can target a seal from a distance, then walk or swim towards it, undetected, until they’re close enough to charge; at other times, they simply sit in wait at a seal’s breathing hole, waiting for the meal to appear; and during seal pupping season in spring, polar bears target seal birth lairs.

How hard is it for polar bears to find food?

Polar bears that are forced to live on land due to melting ice face lean times in most of the Arctic. Food found on land, such as berries and eggs, lack the high fat content and calories of the bears’ preferred prey. Also, catching a seal in open water is far more difficult than catching on the ice.

What causes the polar bear to starve?

Polar bears rely on sea ice to hunt, and when ice is absent, they are forced onto land where they are deprived of food. As Arctic sea ice declines in response to warming temperatures, polar bears must fast for longer periods.

What would happen to polar bears if the ice melted?

A 2020 study found that the melting sea ice is starving polar bears, and that within the century, polar bears could be extinct. As stated in the study, declining genetic diversity increases the risk of extinction.

How long can a polar bear survive without food?

During certain times of the year and under certain conditions the polar bear can survive for up to 8 months without eating any food. This typically occurs when the seasons change and their prey begins to migrate away from the polar bears local grounds.

In fact it takes “approximately 1.5 caribou, 37 Arctic char, 74 snow geese, 216 snow goose eggs or 3 million crowberries” to get the same number of calories as eating one adult seal,” the researchers calculated.

What is the prey of a polar bear?
