Fulmars, Shearwaters and Petrels are Gull-like birds with two nostril tubes located side by side, in a single tube, on the top of the bill at it's base.
The Fulmars are mostly northern birds while the majority of the Shearwaters nest in the extreme south during our winter, and appear off our coasts during the summer. Their food consists of fish or offal which they get from the surface of the water; large flocks of them hover about fishermen, watching their chance to get any food which falls, or is thrown, overboard.
