Over the Ice

During winter months on Antarctica, Adelie penguins migrate north. They make their homes on large platforms of ice. During summer months, the penguins move south to coastal beaches. They look for ice‑free land where they build nests.

To make these trips, penguins follow the sun. But in winter, the sun is hard to find. So, penguins follow the expanding ice that “grows” over the ocean during the cold winter. They live at the edge of this ice.
