. Bulletin - United States National Museum. Science. mm â â Lesser Scaup and White-Winged Scoter, Aythya affinis (see pp. 40, 135, 173) and Melanitta deglandi deglandi (see pp. 43, 135, 176). 7. Residence in the Arctic THE OUTSIDER ENGAGED in arctic exploratioii and exploitation usual- ly follows a program quite different from the native way of life. Travel and construction by nonindigenous methods take place mainly during the few months of open water and unfrozen ground. A year's labor must often be completed within a few months. Haste drives the white man through the arctic summer and he is inclined to think that natural processes move by his schedule. For the natural arctic resident, however, life proceeds at a normal rate in each season. Annual changes in the arctic temperature are large and the progress of related natural phenomena is pronounced because of the con- spicuous character of seasonal transitions. It would be easy to believe that the intensity of seasonal change requires acceleration of those biological processes which must run through their cycle in the arctic summer, for in three months or less birds must terminate their migra- tory flight, mate, nest, rear young, and prepare their departure south- ward. How these important periods are compressed within the short duration of the birds' summer residence in the Arctic is the subject of this chapter. 287.
