There were more than 300 nests in the bird colony when the polar bear arrived.
When it meandered off with a belly full of eggs only 24 nests remained, say scientists who witnessed the “near total” destruction of nests on the bird colony off Baffin Island.
It was far from an isolated event, the team from Environment Canada and Carleton University reported Tuesday.
Hungry polar bears are becoming a bigger threat to seabirds in the Canadian Arctic than traditional nest robbers like foxes and gulls, the researchers say in a study that points to the “cascading ecological impacts” of climate change.
