Bulweria bulwerii
Bulweria fallax

Bulweria is a genus of seabirds in the family Procellariidae named after English naturalist James Bulwer. The genus has two living species, Bulwer's Petrel (B. bulwerii) and Jouanin's Petrel (B. fallax). A third species, the Small Saint Helena Petrel, (Bulweria bifax) became extinct in the early 16th century; it is known only from skeletal remains.

Bulweria petrels have long been considered related to the gadfly petrels in the genus Pterodroma, but recent mtDNA cytochrome b sequence analysis has proven them to be closely related to the shearwaters in the genus Puffinus and especially the Procellaria petrels (Bretagnolle et al., 1998).
