Bulweria

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.
