Although seabirds are locally superabundant in the vicinity of breeding colonies, abundance farther offshore is patchy in both space and time. The present study examines the fine-scale (i.e. 1 km unit) distribution and abundance of four seabird species as a function of distance from a breeding colony (for three of the four species) and nekton density determined hydroacoustically. We found that density of the breeding species was significantly associated with nekton density, after controlling for island effects. In addition, nekton density associated with foraging aggregations of seabirds was significantly higher than that under resting aggregations. These results provide some of the clearest evidence of seabird-nekton association, albeit on an extremely close spatial scale.
