General comparison of computations of the seal herd on the Pribilof Islands, 1926 



to 1937 



FOXES 



A herd of blue foxes is maintained on each of the two principal 

 islands of the Pribilof group, where the animals roam at large and 

 obtain their food during most of the year from birds, birds' eggs, and 

 miscellaneous sea life abundant on the beaches. In the winter, when 

 the natural supply of food is scarce, the foxes are fed prepared ra- 

 tions, consisting chiefly of biscuits made of cereals, seal meal, and 

 seal oil. In December and January the animals are trapped for their 

 pelts and a suitable number are reserved for future breeding require- 

 ments. 



TRAPPING SEASON OF 1937-38 



In the 1937-38 season there were taken 863 fox pelts, of which 847 

 were blue and 16 white. Two hundred and tliirty-one blue and 15 

 white pelts were taken on St. Paul Island and 616 blue pelts and 1 

 white pelt on St. George Island. 



There were trapped, marked, and released for breeding stock 59 

 male and 56 female foxes on St. Paul Island and 44 males and 41 

 females on St. George Island. The breeding reserve includes also a 

 considerable number of animals that were not captured during the 

 season.
