Summary Pelagic seabird populations have declined strongly worldwide. In the North Atlantic there was a huge reduction in seabird populations following the European colonization of the Azores, Madeira and Canary archipelagos but information on seabird status and distribution for the subtropical region of Cabo Verde is scarce, unavailable or dispersed in grey literature. We compiled and compared the historical and current distribution of all seabird species breeding in the Cabo Verde archipelago, updated their relative abundance, investigated their inland habitat preferences, and reviewed their threats. Currently, the breeding seabird community in Cabo Verde is composed of Bulwer’s Petrel Bulweria bulwerii , White-faced Storm-petrel Pelagodroma marina aedesorum , Cape Verde Shearwater Calonectris edwardsii , Cape Verde Storm-petrel Hydrobates jabejabe , Cape Verde Petrel Pterodroma feae , Boyd's Shearwater Puffinus lherminieri boydi , Brown Booby Sula leucogaster , and Red-billed Tropicbird Phaethon aethereus . One breeding species is currently extinct, the Magnificent Frigatebird Fregata magnificens . The relative abundance of Cape Verde Shearwater, Boyd’s Shearwater, Cape Verde Petrel, and Cape Verde Storm-petrel was determined from counts of their nocturnal calls in Santo Antão, São Vicente, Santa Luzia, Branco, Raso and São Nicolau. Cape Verde Petrel occurred only on mountainous islands (Santo Antão, São Nicolau, Santiago, and Fogo) from mid-to high elevations. Larger spec...
