List of Procellariidae
The taxonomy of the Procellariidae, or procellariids, is complex and still a matter of some debate. The traditional taxonomy breaks the procellariids into four main groups, the fulmarine petrels, the prions, the gadfly petrels and the shearwaters. Recent studies have called this arrangement into question.
This traditional taxonomy is based upon Carboneras (1992) in the Handbook of the Birds of the World.
Based on Austin (1996), Bretagnolle et al. (1998), Nunn & Stanley (1998) and Brooke (2004), several changes have been made from the more traditional taxonomy. The two species in the genus Bulweria are no longer considered close to the rest of the gadfly petrels; several more gadfly petrels are removed from Pterodroma and placed in Pseudobulweria (allied to the shearwaters), and the Kerguelen petrel is also removed from Pterodroma and placed in the monotypic Lugensa. Several taxa are also elevated to species status on the basis of newer studies.
An undescribed prehistorically extinct species was found on Easter Island. For other non-Recent extinctions, see the genus accounts.
