MOVEMENT 



ON THE BREEDING GROUNDS 



There is little published literature regarding movement within the breeding grounds. Kuchel 

 (197.7) found that pairs used lower McDonald Creek prior to establishing home ranges higher in 

 the stream. Once established, pairs rarely moved more than 1-2 km, although movements of up to 

 8 km were recorded. Kuchel (1977) found unpaired males moved considerably more, with 

 movements of up to 10 km found. In a reanalysis of Kuchel's (1977) data, Cassirer and Groves 

 (1992) found that linear home ranges averaged 7.7 km (5D = 2.34) on McDonald Creek, similar 

 to the 7 km reaches used in Idaho. 



On the Bow River in Banff National Park, 5 pairs of birds were marked at what is probably a 

 staging area or local migratory corridor (Smith 1996). Two pairs remained in a 2 km section of 

 river where they were banded and another remained in a 2 km stretch about 12 km downstream; 

 one pair remained within about 6 km until the female moved about 8 km up a drainage, perhaps to 

 breed; the final pair moved about 15 km downstream within 22 days (Smith 1996).
