MIGRATION'S OF WHALES KELLOGG 487 



1915, p. 115.) On February 1, 1911, blue whales were sighted at 

 166° 17' west longitude and 78° 38' south latitude. In March they 

 were seen near 67° south latitude and 161° east longitude. Thus it 

 is evident that blue whales frequent the pack ice and the ice-chilled 

 seas in the latitude of Victoria Land and Wilkes Land south of New 

 Zealand during the Antarctic summer and that their northward 

 migration, if such occurs, does not closely approach the New Zealand 

 coastal waters. Waite has recorded occurrences of blue whales in 

 Spencer Gulf and Corvisart Bay on the coast of South Australia. 



The taking of blue whales in San Bartolome Bay and near Asun- 

 cion Island, Lower Calif., between latitudes 27° and 28° north are 

 reported by Scammon (1874, p. 72). The same writer refers to the 

 presence of large numbers of these whales off San Quentin and off 

 Cedros Island, Lower Calif., in July. On July 17, 1928, several blue 

 whales were sighted by "W. L. Cruickshank, captain of the British 

 banker THnculo^ in the Pacific Ocean off Nicaragua at 11° 32' north 

 latitude and 91° 58' west longitude. The records of the whaling 

 stations on the Pacific coast indicate that blue whales occur at all 

 seasons off the coast of California. From May to September blue 

 whales are found close to the shore, where low surface temperatures 

 result from the upwelling of cold bottom water with the prevailing 

 offshore winds. In recent years blue whales have been infrequent 

 visitants along the California coast, for not more than five were 

 taken at Moss Landing from January 16, 1919, to May 3, 1922. An 

 80-foot blue whale was harpooned off southern California in the 

 vicinity of San Clemente Island on July 15, 1927. They occur more 

 frequently off Vancouver Island, for three were taken at Rose Harbor 

 and seven at Haden Harbor in 1927. They first appear off Kyuquot, 

 Vancouver, in March. (Andrews, 1916, p. 24.) 



Blue whales are most abundant off the coasts of Japan during the 

 winter and are infrequently killed during the summer. (Andrews, 



1916, p. 327.) 



FINBACK (BALAENOPTERA PHYSALUS) 



The migration routes of finbacks are not so well known as those 

 of humpbacks, and the observed facts of gestation indicate that their 

 journeys do not have any especial connection with their breeding 

 habits. Their diet is subject to seasonal change and includes herring, 

 capelan, and at times plankton. Climate seemingly has little in- 

 fluence in curtailing their wanderings, for finbacks appear to be in- 

 different alike to Tropic and Arctic temperatures, and travel where 

 they will. 



Finbacks are distributed over the North Atlantic according to 

 season from Spitzbergen and Greenland southward to the Azores. 

 Although they are much swifter swimmers than the humpbacks, 

 they go to and from the same northern oceanic regions. On the
