Chasing Guano: The Discovery of a Penguin Supercolony

When scientist Heather Lynch came across a satellite image of the Antarctic Peninsula's remote Danger Islands streaked with pink, she knew exactly what she was looking at...Poopâ guano, to be more specificâ and a lot of it. The culprit, she suspected, was a previously unnoticed colony of penguins. A big one. And their favourite food appeared to be pink krill. For a closer look, Heather built a team for an expedition to the Danger Islands, an area notorious for its unpredictable sea ice. Penguins are particularly important to study because, as indicator species, they can alert scientists to issues affecting the larger ecosystem. Join Heather and her team on a fascinating exploration of these remote islands as they discover a supercolonyâ home to one of the world's largest populations of AdÄlie penguins.
