Living in the Antarctic region, Adelie penguins must withstand very cold temperatures. During the winter months they inhabit large coastal ice platforms, so they will have better access to food. Krill, the primary staple in their diet, feed on plankton that live underneath sea ice, so there is an abundance of krill in those areas. During the breeding season, typically in the early spring and summer months, they travel to coastal beaches to build their nests on ice-free ground. With access to open water, this locale provides the penguins with almost immediate access to food for themselves and their young. (Alten, 1997; Berger, 2004; George, 2002)
