Foraging range scales with colony size in high-latitude seabirds
Density-dependent prey depletion around breeding colonies has long been considered an important factor controlling the population dynamics of colonial animals. 1–4 Ashmole proposed that as seabird colony size increases, intraspecific competition leads to declines in reproductive success, as breeding...

Density-dependent prey depletion around breeding colonies has long been considered an important factor controlling the population dynamics of colonial animals. 1–4 Ashmole proposed that as seabird colony size increases, intraspecific competition leads to declines in reproductive success, as breeding adults must spend more time and energy to find prey farther from the colony. 1 Seabird colony size often varies over several orders of magnitude within the same species and can include millions of individuals per colony. 5, 6 As such, colony size likely plays an important role in determining the individual behavior of its members and how the colony interacts with the surrounding environment. 6 Using tracking data from murres (Uria spp.), the world's most densely breeding seabirds, we show that the distribution of foraging-trip distances scales to colony size 0.33 during the chick-rearing stage, consistent with Ashmole's halo theory. 1, 2 This pattern occurred across colonies varying in size over three orders of magnitude and distributed throughout the North Atlantic region.
