The vernacular name "puffin" – puffed in the sense of swollen – was originally applied to the fatty, salted meat of young birds of the unrelated species Manx shearwater ("Puffinus puffinus"), which in 1652 was known as the "Manks puffin". It is an Anglo-Norman word (Middle English "pophyn" or "poffin") used for the cured carcasses.
Tropical shearwater subspecies thought to number 3,000–5,000 pairs on Réunion and fewer than 100 individuals on Europa (reviewed by Brooke 2004), though it is thought there are many more breeding colonies on other islands in the Pacific. The population seems to be stable.
