It emits a characteristic plaintive and shrill sound in breeding areas, while in flight in the open sea it is silent. It is a seabird observable on the island from spring to autumn: a good place to stand is the capes on the coast, much better if it is in the evening hours.
The Cory’s shearwater (Calonectris diomedea) is a species of procellariform bird of the family Procellariidae found in the Mediterranean and the Atlantic.
It is a seabird that spends most of the year offshore and only comes to the Mediterranean coasts to breed. It feeds mainly on squid, which it hunts by hovering near the surface of the sea. It is somewhat smaller than the Atlantic shearwater. As its name indicates, it has brown upper parts, while its lower parts are white, except for the edges of its long wings, which are brown. It was chosen bird of the year 2013 by SEO/BirdLife.
