OFF ANVERS ISLAND, Antarctica (Reuters) - The number of chinstrap penguins in some colonies in Western Antarctica has fallen by as much as 77% since they were last surveyed in the 1970s, say scientists studying the impact of climate change on the remote region.
The chinstrap penguin, named after the narrow black band under its head, inhabits the islands and shores of the Southern Pacific and Antarctic Oceans and feeds on krill.
