left by the second pair survey of Marten Creek on 26 May. The last male was seen on McDonald 

 Creek on 22 June 1992 about 10 days earlier than reported in 1973-75 (Kuchel 1977, Ashley 

 1993). All young were nearly fledged by the end of July on the Lower Clark Fork drainages and 

 13 August on Trail Creek. However, most females and young were still present on 10-11 August 

 at McDonald Creek in Glacier National Park, and some young were still downy.
