Variations in Nest Mortality in the European Storm Petrel Hydrobates Pelagicus
Procellariformes breed mainly on inaccessible islands and many species nest underground reducing egg or chick losses caused by predation. Nevertheless, Procellariformes show low reproductive rates. In a four years study of breeding European Storm Petrel, we estimated nest mortality for three stages:...
