Great Shearwater (Puffinus gravis)

"In calm weather, they are fond of alighting on the water, in company with the Fulmars, and are then easily approached. They swim buoyantly, and have a graceful appearance while playing among themselves. Two that had been caught with hooks, walked as well as Ducks, and made no pretence of sitting on their rumps, as some writers have said they do. On being approached, they opened their bills, raised their feathers, and squirted an oily substance through their nostrils, which they continued to do when held in the hand, at the same time scratching with their sharp claws and bills. They refused all sorts of food; and as they were unpleasant pets, they were set at liberty. To my great surprise, instead of flying directly off, as I expected, they launched toward the water, dived several yards obliquely, and on coming to the surface, splashed and washed themselves for several minutes before they took to wing, when they flew away with their usual ease and grace."

John James Audubon (1840) in Birds of America, Vol. VII.
