MONOGRAPH OF THE PETRELS. 



from the same locality obtained in the month of March, which has a grey neck, similar 

 to one from Stewart Island, obtained in December, 1814. The same collection includes 

 two birds from the Macquarie Islands captured in October, 1899, but both have pure 

 white throats. Mr. Campbell says that P. urinatrix is found in the seas of New South 

 Wales, Victoria, and South Australia (Nests and Eggs Austr. Birds, p. 919), and Gould 

 observed that it was very abundant in Storm Bay, Tasmania. 



P. urinatrix occurs again in the Straits of Magellan, and I am unable to perceive 

 any difference in specimens from the extreme south of South America and those from 

 New Zealand. No species of Pelecanoides is recorded by Wiglesworth from the Pacific 

 Ocean in his " Aves Polynesia," nor has P. urinatrix been met with in the South Indian, 

 or South Atlantic Oceans. On Kerguelen and the Crozet Islands P. exsul only has been 

 found, but Professor Giglioli during the voyage of the " Magenta " shot two specimens 

 of P. urinatrix in the Channels of Western Patagonia, and a few days later procured a 

 third example, at Playa Parda, near the western entrance to the Magellan Straits. 



These birds are seldom seen in the open sea, but among the few instances 

 mentioned is one by Dr. E. A. Wilson of the " Discovery," which probably referred 

 to P. exsul (vide infra), and another by Gould (Handb. Birds Austr., p. 483), who 

 observed a species of Pelecanoides about 20° east of New Zealand ; it was feeding 

 on some small animals close to the surface of the water, now diving and rising again, 

 skimming close to the surface, and then flying off in a straight line with a quick 

 fluttering motion of the wings. 



The British Museum contains specimens of a Pelecanoides from South America, 

 which, following Salvin, I refer to P. urinatrix. In addition to the Falkland Islands 

 birds in the Museum, there are others from Cockle Cove, Antonio Island, and Wood's 

 Bay in the Straits of Magellan, obtained by Dr. Coppinger, during the cruise of H.M.S. 

 " Alert," and others were procured by H.M.S. " Challenger " in Cove Harbour, Messier 

 Channel (Salvin, Cat. Birds Brit. Mus., XXV., p. 438). Darwin, in the " Voyage of 

 the ' Beagle ' " (II., p. 138), says that the bird was common in the deep and quiet creeks 

 and inland seas of Tierra del Fuego, and on the west coast of Patagonia as far north as 

 the Chonos Archipelago; only once did he observe it on the open sea, between 

 Tierra del Fuego and the Falkland Islands. Mr. M. J. Nicoll, during the cruise of the 

 " Valhalla," obtained specimens in Molyneux Sound, Smythe's Channel. Dr. E. A. 

 Wilson also records a Pelecanoides in the Straits of Magellan in July (Nat. Antarct. 

 Exped., Aves, p. 107), and Captain Crawshay includes the species in the avifauna of 

 Tierra del Fuego, a specimen having been blown ashore in Useless Bay (Birds of Tierra 

 del Fuego, p. 143). 



The Diving Petrel well deserves its name from its distinctive habits, while in 

 consequence of its weak flight, it is chiefly an inhabitant of the still waters of sheltered 

 bays. 



Although widely differing in structure, P. urinatrix, in appearance, closely resembles
