アラビアアナドリ Bulweria fallax

An all-dark, pigeon-sized petrel. Very bulky, with broad wings and a heavy, dark bill. Similar to Bulwer’s Petrel, but Jouanin’s appears heavier overall with a shorter tail, a larger bill, and no white on the wings. Strong flier, gliding often with occasional wingbeats, and staying close to the water.
