metabolic effort. This physiological adaptability obviates environ- 

 mental stress. No animals, least of all small birds, can act in conflict 

 with arctic conditions. Individual and social behavior must direct 

 animals to localities, and at those seasons, when conditions are well 

 within the physiological tolerance of the population. 



Our studies are still in progress. From them we can expect 

 continuing contributions to our knowledge of animal adaptation to 

 the arctic environment. Some of this knowledge, we can hope, will 

 have special meaning for the citizens of our newest State, Alaska, 

 and for all others who dwell in regions of intense cold.
