Where the Adelie penguin breeds, the whole area is reddened by the pigment of the ephausid crustaceans in the dung of the birds. At the beginning of winter the breeding places are abandoned; the penguins range north- ward in the sea, following the borders of the pack ice. Pygoscelis adeliae migrates still further northward and does not return to its breeding places before the regular breeding season, even if ice condi- tions Like the auks, penguins have only a single egg (rarely two) and brood this by pressing it into a featherless brood pocket situated posteriorly on the belly, protecting it from below with the feet (Fig. 126).
