520 3# ‡aResearch at two colonies of Adélie penguins on Ross Island from 1999-2001 showed that colony size positively correlates to foraging trip duration and metabolic rate; that metabolic rate while foraging may be approaching energetic ceiling for birds at largest colonies; and that total energy expended increases with trip duration although uncompensated by increased mass gain. Results indicate that competition-induced reduction in prey availability results in higher energy expenditure for birds foraging in halo around large colonies, and that to escape halo birds must increase foraging distance until net cost of foraging trips becomes too high, with chicks receiving insufficient food, when chick survival suffers and subsequent colony growth is limited.
