Are Polar Bears Going to Eat Geese Into Extinction

 

Polar bears are known to raid geese nests to help sustain the bear population. This leads to a growing concern of geese extinction in the Arctic. However, a newly released study published in an early online edition of Oikos, it is concluded that there is going to be a mismatch in the timing of bear arrival on shore and goose egg incubation.

In previous years, it was observed that as the bears came for the goose eggs, the eggs were already hatched into goslings that were long gone by the time these bears came. Recently, there has been a changing trend and “early” bears come ashore just in time to consume the eggs. The earlier they come, the better nutrient value they will get from the young embryo.

The mismatch is considered good by the environmentalists who continually study the timing of events: the break-up of sea ice, the movement of bears onto shore, the migration of geese to the North, and the laying of eggs. Te mismatch keeps the geese from going extinct and yet allowing polar bears their share to eat.
