DIURNAL ACTIVITY OF ADELIE PENGUINS PYGOSCELIS ADELIAE AT CAPE BIRD
SUMMARY Activity cycles of non‐breeding Adelie Penguins were investigated at Cape Bird, Antarctica. There was continuous light during the observation period, but none the less regular fluctuations of light intensity and temperature were maintained. The penguins had no single period of rest, but were...
