ソロモンミズナギドリ Pseudobulweria becki

A mostly dark-brown petrel with a white underbody and a strongly hooded appearance. Very similar to the larger Tahiti Petrel, but has a smaller, thinner bill and more rounded wings. Erratic flight style is much more fluid and “flappy” than that of Tahiti Petrel, which prefers to soar endlessly on long thin wings. Similar to Phoenix Petrel, but lacks a pale throat and a pale bar on the leading edge of the underwing.
