Procellariidae

Bulweria Petrels

The Bulweria Petrels are formed by only two species rather closely related to the fulmarine petrels. Both are dark brown birds. The genus is represented in the three major oceans by the Bulwer's Petrel. The larger but otherwise similar Jouanin's Petrel is restricted to the Indian Ocean.
