Tracking of Cory's Shearwaters

From 2007 the researches of Ornis italica
are tracking Cory's Shearwaters from the little
island of Linosa (Italy) in a cooperation with
the University of Palermo (IT) and Montpellier (FR)
Linosa is a small island placed at around 150km between the southern coast of Sicily and the coast of Libya. Despite the relatively small size of the island, it hosts the second largest colony of this species in the Mediterranean Sea, with an estimated number of about 10'000 pairs. While this colony is relatively healthy, the Mediterranean subspecies of Cory's Shearwater is undergoing a decline similar to other pelagic species due to overfishing, predation by rats and feral cats, human related losses and colony disturbance.
From 2007 we followed about 80 Cory's Shearwaters during their foraging trip with GPS loggers from Technosmart, mainly during the chick rearing period, from July to August. The first results from these studies can be seen here.
In 2009 we then proceeded with the use of Geolocators, to locate the wintering grounds of this subspecies, which seem to be located off of the western African coasts.
From 2010 we started also to track the very small colony of Salina (Eolie Islands) north of Sicily, which seems very endangered due to rats.
