Niche switching and leapfrog foraging: movement ecology of sympatric petrels during the early breeding season
Abstract Background The timing of events in the early part of the breeding season is crucially important for successful reproduction. Long-lived animals that migrate large distances independently of each other meet at the breeding sites to re-establish their pair bonds and coordinate their breeding...
