  abstract = {{C}auses and consequences of differences in seabird foraging strategies between breeding colonies are not well understood. {W}e tested whether body size of a pursuit-diving seabird, the thick-billed murre {U}ria lomvia, differs between breeding colonies and, if so, how size differences can be understood in the context of differences in foraging behavior, habitat use, and breeding performance. {W}e measured adult murres over 3 seasons (2008 to 2010) at 2 of the {P}ribilof {I}slands, {S}t. {P}aul and {S}t. {G}eorge, located on the continental shelf of the {B}ering {S}ea at different distances from the shelf break. {B}ody mass and size were positively associated with deep diving and negatively associated with long flights, suggesting morphology influences foraging and commuting efficiency. {M}urres from {S}t. {P}aul (farther from the shelf break) were larger than those from {S}t. {G}eorge (nearer the shelf break), foraged exclusively in the middle shelf domain, made deep dives during daylight, and fed on larger benthic prey. {I}n contrast, smaller murres from {S}t. {G}eorge commuted greater distances to beyond the shelf break, made shallow dives at night, and fed on smaller, high-energy, schooling, vertical-migrating prey. {B}oth foraging strategies resulted in similar chick-feeding rates and fledging success. {T}he largest and the smallest murres experienced less stress during breeding compared to intermediate-sized murres, suggesting divergent selection for body size between islands. {N}esting murres, as central-place foragers, may experience strong selection pressure on body size and other adaptive traits that reflect differences between breeding colonies in foraging ecology and the acquisition of resources for reproduction.},
