    Pachyptila is a genus of seabirds in the family Procellariidae and the order Procellariiformes. The members of this genus and the blue petrel form a sub-group called prions. They range throughout the southern hemisphere, often in the much cooler higher latitudes. Three species, the Broad-billed Prion (Pachyptila vittata), the Antarctic Prion (Pachyptila desolata) and the Fairy Prion (Pachyptila turtur), range into the subtropics.
