About

The Balearic shearwater (Puffinus mauretanicus) is a medium-sized shearwater in the seabird family Procellariidae. Puffinus is a Neo-Latin loanword based on the English "puffin" and its variants, that referred to the cured carcass of the fat nestling of the Manx shearwater, a former delicacy. The specific mauretanicus refers to Mauretania, an old name for an area of North Africa roughly corresponding to Morocco and Algeria.
