" The Fulmar is a constant attendant on" whalers, sealers, etc. — who 

 know it as the ' Mollinioke' — in order to obtain fatty substances and 

 animal offal ; but I never saw it take any while on the wing, and it 

 always settles on the water to feed, like an Albatross. The pinions 

 are often flapped slowly in an owl-like manner, but in scudding they 

 are held very straight — a peculiarity by which it may easily be distin- 

 guished from a Gull at a distance " (Saunders).
