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 napped 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 PINTADO PETREL (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).
