Cape Verde shearwater
The Cape Verde shearwater ("Calonectris edwardsii"), or cagarra locally, is a medium-large shearwater, a seabird in the petrel family Procellariidae. It is endemic to the Cape Verde archipelago of Macaronesia in the Atlantic Ocean, off the coast of West Africa.
Taxonomy.
The Cape Verde shearwater was originally described in 1883 by Émile Oustalet as a full species. It was later lumped as a subspecies of Cory's shearwater but has since been separated again, by Cornelis Hazevoet in 1995
Boyd's shearwater
Boyd's shearwater ("Puffinus boydi"), also known as the Cape Verde little shearwater, is a small shearwater which breeds in the Cape Verde archipelago of the Atlantic Ocean some 570 km off the coast of West Africa. The epithet commemorates British ornithologist Arnold Boyd.
Taxonomy.
Boyd's shearwater is sometimes considered a subspecies of either the little shearwater, Audubon's shearwater or Macaronesian shearwater. It has also been shown to be synonymous with the extinct "Puffinus parvus" Shufeldt of Bermuda
