Diet and diving behaviour of European Storm Petrels Hydrobates pelagicus in the Mediterranean (ssp. melitensis).

Capsule Unlike Atlantic populations, which feed on krill, Mediterranean populations feed mainly on pelagic fish Gymnammodites cicerellus. Aims To determine the diet and dive depth of the Mediterranean subspecies of European Storm Petrels Hydrobates pelagicus melitensis. Methods Analysis of regurgitates of adults arriving at the colony for chick feeding and by determination of dives depth using the capillary tube method. Results The main prey is Gymnammodites cicerellus, a pelagic fish. Storm Petrels dive for their prey and can reach up to 5 m in depth. They also make short foraging trips just outside the colony where they capture Opossum Shrimps Misydacea. Conclusions European Storm Petrels…
