フィージーミズナギドリ Pseudobulweria macgillivrayi

A relatively small, entirely dark petrel, appearing chocolate-brown or black, with a distinctive short-necked and cigar-shaped silhouette due to its tapering tail. Lacks the white underside of the otherwise similar Beck’s Petrel, and is significantly smaller than and lacks the white belly of Tahiti Petrel. Similar to Bulwer’s Petrel, but lacks the pale bars found in the upperwing of that species, appears shorter-necked, and does not hold its head high in flight. Overall flight style of Fiji Petrel is more acrobatic than that of Bulwer’s Petrel.
