Very up close and in flight also, you can see the webbed yellow. It differs from the European Storm-Petrel clear his band greater coverts and absence of the white stripe in the center of the bottom of the wing. From Storm-Petrel Boreal by broad and rounded wings that keep rather straight instead of bent and tail with square end.
