174 FULMARS, SHEARWATERS, PETRELS 
The young are hatched covered with down, usually sooty or gray in 
color, and are reared in the nest. When taken from the nest, both old 
and young usually disgorge a quantity of amber-colored oil, the strong 
odor of which always characterizes the burrows or cavities in which 
most of these birds nest.

“The Fulmar is a constant attendant on whalers, sealers, etc.—who 
know it as the ‘Mollimoke’—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 pecularity by which it may easily be distin- 
guished from a Gull at a distance’ (Saunders). 
The Pinrapo Petrrep (102. Daption capense) of the Southern Hemisphere 
has been once recorded from Maine (Purdie, ‘‘New England Bird-Life,”’ p. 
387; see also Knight’s ‘Birds of Maine,” p. 67).
