lion are considered possible. Larvae reach 

 the belly blubber of pups 4 to 6 days after 

 entering the pups' flippers. The route of 

 migration may be subcutaneous since none 

 have been found in the blood. 



OTHER WILDLIFE SPECIES 



SEA LIONS 



Sea lion pups were not tagged on Walrus 

 Island in 1962. No recoveries have been made 

 from 100 pups tagged in 1959 and from 530 

 tagged in 1960. 



WHALES 



Three dead whales drifted ashore on the 

 Pribilof Islands in 1962, a humpback whale 

 (Megaptera novaeangliae) and little piked or 

 minke whale (Balaenoptera acutorostrata) on St. 

 George Island and a little piked whale on St. 

 Paul Island. 



WALRUS 



In 1962, five walruses (Odobenus rosmams 

 divergens) were found dead on beaches of the 

 Pribilof Islands, as follows:

SEA OTTER 



Donald Boggs, sighted what he iden- 

 tified as a sea otter (Enhydra lutns) swimming 

 on its back off Southwest Point, St. Paul 

 Island several times during March, April, and 

 May 1962, If the record is authentic, the animal 

 presumably is one of seven sea otters trans- 

 planted to St. Paul Island from Amchitka 

 Island in 1959, 



A party of about 20 individuals visited Otter 

 Island in 1 July. No sea otters were observed. 



REINDEER 



A thorough search of the island on 9 August 

 yielded a total estimate of 726 reindeer, of 

 which 700 were together north of Fox Hill at 

 its base. A single bull was sighted on Ridge 

 Wall, another on the flat south of Crater Hill, 

 and 24 reindeer were located on the flat 300 

 yards south of Tsammana Lake. The estimate 

 of 726 agrees with a count of 707 obtained 

 1 July as the reindeer grazed or rested in the 

 approach to the corral on Lake Hill. 



The southwest portion of St. Paul Island is 

 showing the effect of overgrazing by the 

 rapidly increasing reindeer herd. A more de- 

 tailed report on the reindeer herd will be 

 filed by management officials following the 

 autumn harvest which will supply a large 

 amount of meat and keep the size of the 

 reindeer herd at a level where range damage 

 is minimized. 



COOPERATIVE STUDIES 



The following summaries of work done by 

 cooperators were partially prepared by the 

 cooperator or from information furnished by 

 him. 



William G. Reeder and James W. 

 Nybakken from the University of Wisconsin, 

 spent the period 7 to 20 July on St. Paul 

 Island making a preliminary study of fur 

 seal vocal patterns, particularly those con- 

 tributing to mother-young recognition. Using 

 recording equipment with satisfactory fre- 

 quency response from about 50 to 15,000 

 cycles per second, initial recordings were 

 made of the miscellaneous vocalizations typical 

 within the harem; these included sounds asso- 

 ciated with male aggression, herding, copula- 

 tion, female aggression, supplication of male, 

 and pup calling. During the latter part of the 

 study three pregnant females were held in 

 field cages. When two of these gave birth, 

 recordings were made of the vocalization of 

 the female just before parturition, and, more 

 importantly, the mutual calling of mother and 

 young immediately after birth. It was hypothe- 

 sized that individual patterns and quality of 

 vocalizations were mutually learned at this
