The case of the missing Emperor penguins

Emperor penguins are icons of the penguin world. They are only found in the wild in Antarctica and breed and raise their babies on the ice. Because the Antarctic is so massive and difficult to explore, scientists rely on satellite images to detect colonies and the penguins’ activities.

Once a year penguins shed all their feathers on the ice and replace them with new ones. The feathers they leave behind can also be seen on satellites - but now scientists are worried. Recently they haven’t seen much evidence of this “mega moult”. BBC climate and science correspondent Georgina Rannard explains what this could mean for the Emperor penguin populations.

And finally, Ash from the What in the World team brings a few more animal stories she’s spotted this week, including an update on viral sensation Punch the Monkey, in Ichikawa City Zoo in Japan.
