This is a strictly pelagic seabird, inhabiting the open waters of the South Atlantic, primarily breeding on steep, vegetated slopes and plateaus of a remote oceanic island.
Their diet primarily consists of cephalopods (squid), various fish species, and crustaceans. They are opportunistic feeders, frequently scavenging offal from commercial fishing boats.

They are highly efficient foragers, employing surface-seizing and shallow pursuit-diving techniques, and frequently assoc...

After breeding, these pelagic birds disperse widely across the eastern and central South Atlantic. Their non-...
