Antarctic penguin count reveals dramatic decline2020|02:40
Researchers have found that a certain species of Antarctic penguin has seen a massive fall in its population. Named for its distinctive black line underneath its head, the chinstrap penguin calls the Southern Pacific and Antarctic Oceans home. But some colonies in Western Antarctica have shrunk by as much as 77% since they were last surveyed in the 1970s, according to the scientists from Northeastern and Stony Brook universities. They traveled on two Greenpeace ships earlier this year, using manual and drone surveillance to assess the damage. Reuters' Stuart McDill joined the crew.
