Disentangling the effects of predation and oceanographic fluctuations in the mortality of two allopatric seabird populations

Life‐history traits of migratory seabirds are influenced by changing conditions at breeding and wintering grounds. Climatic conditions and predation are known to impact populations’ survival rates, but few studies examine their effect simultaneously. We used multievent capture–recapture models to assess mortality due to environmental conditions and predation in breeding European storm petrels ( Hydrobates pelagicus ) in two allopatric colonies...
