AVES PUFFINID^E. 149 



Color. Adult Male. Uniform dark chocolate brown throughout; the 

 edges of all the feathers a little paler than the other portion. 



Bill yellow. 



Tarsi black. 



Feet black. 



"Male: Tom Bay, April 13, 1879. Bill light grey; iris dark brown ; 

 eyelids black ; legs and feet dark grey." (Sharpe, P. Z. S. 1881, pp. 

 11-12.) 



Young and immature birds are lighter brown, more or less mottled 

 with dull white and white about the head ; the edges and tips of many 

 of the dark feathers are also dull white. The under parts vary from almost 

 pure white to a condition of color approaching the adult. Nearly white 

 individuals are occasionally met with. 



Geographical Range. Southern Oceans, north regularly to 30 South 

 Latitude. Casually on the Pacific coast of North America to Oregon. 



The Giant Fulmar was not obtained by the Princeton Expeditions to 

 Patagonia. The material examined as a basis for the above description 

 is in the Collections of the Academy of Natural Sciences of Philadelphia, 

 and in the British Museum of Natural History. 



" Lays a single egg on open, rather elevated ground, at some distance 

 (half a mile) from the sea. There was no vestige of an artificial nest 

 when the young were found, January 2. These were then nearly fledged, 

 and quite as large and heavy as the adults, occupying natural hollows 

 between mounds of Azorella. They are exceedingly filthy birds, ejecting 

 the contents of their stomachs for two or three feet from their bodies, and 

 seeming to have a limitless supply to draw upon. When disturbed, they 

 are soon surrounded by a puddle of vomited matters, and are, in this 

 condition, by no means pleasant birds to collect. Among the ejecta were 

 noticed many Penguin feathers. In the same neighborhood was a young 

 bird of an earlier brood, fully fledged, but not yet able to fly. These 

 Petrels must therefore be among the earliest in laying. The down of the 

 young bird is entirely grey in color, the head is partly naked, and the 

 bill, tarsi, and feet are colored nearly as in the adult, but somewhat paler. 

 The first fully formed feathers are similar to the adult plumage."
