Cape Verde Shearwater

Calonectris edwardsii (Oustalet, 1883)

Cape Verde Shearwater, Calonectris edwardsii, breeds on islands in the Cape Verde archipelago in the Atlantic Ocean west of north-west Africa, and it ranges outside the breeding season to waters off west Africa, southern Brazil and northern Argentina. It is a seabird in the petrel family Procellariidae. The bird has a slim, dark bill, and its head and upperparts are darker than Cory’s Shearwater. It was first described in 1883 by Émile Oustalet and later recognised again as a separate species.
