 know it a.s the ' Molliinoko' — in ordor to ohlaiii fatty substances and 

 animal offal : but I never saw it take any while on the vvinj?. 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 nuiy easily be distin- 

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