Pseudobulweria vs. Pterodroma
Clements (2010) and Sibley & Monroe (1996) place Mascarene Petrel, Tahiti Petrel, Beck's Petrel and Fiji Petrel in Pterodroma. However, Howard & Moore, 2003, Brooke 2004, Christidis & Boles 2008, and Gill & Donsker 2010 recognise the genus Pseudobulweria.
Moist lowland forests, montanes, shrubland, open seas and rocky shores.
