List of Procellariidae species
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. Traditional taxonomy. This traditional taxonomy is based upon Carboneras (1992) in the "Handbook of the Birds of the World". Fulmarine petrels Gadfly petrels Prions Shearwaters Revised taxonomy. 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.
