Bat populations are plummeting from a seemingly unstoppable fungal infection. Meanwhile, northern flying squirrels are being crowded out by their southern cousins. Learn about the life-or-death challenges faced by key wildlife in two of the Great Lakes region's most delicate ecosystems.

This episode describes the migration of most animals northwards (some from the Antarctic continent, others from the few islands surrounding it) as the continent and surrounding sea freeze over at the end of summer. It shows how young penguins often fall prey to Leopard Seals as they try to make their way across the already partially frozen water and how their stripped remains become food for isopods and meter-long nemerteans (ribbon worms). Before going to the sea, however, the adult penguins must shed their coats (molting).

This programme focuses on birds. The feather is key to everything that is crucial about a bird: it is both its aerofoil and its insulator. The earliest feathers were found on a fossilised Archaeopteryx skeleton in Bavaria. However, it had claws on its wings and there is only one species alive today that does so: the hoatzin, whose chicks possess them for about a week or so. Nevertheless, it serves to illustrate the probable movement of its ancestor. It may have taken to the trees to avoid predators, and over time, its bony, reptilian tail was replaced by feathers and its heavy jaw evolved into a keratin beak.
