Polar bears forced to eat eggs as climate change shrinks Arctic hunting grounds, shows study using drones
Polar bears are increasingly foraging on seabird eggs as climate change shrinks their Arctic hunting grounds.
Using drones, researchers in Canada tracked the feeding pattern of polar bears. It is well known that climate change has brought polar bears to the verge of starvation.
Earlier this month, a paper published in the journal Global Change Biology found that polar bears maintained highly specialized diets of soft blubber and flesh for hundreds of years -- even during previous periods of Arctic warming.
In July, a study published in Nature Climate Change estimated the species would be starved to extinction by 2100.
