Abstract:
Surveys were conducted to gain more information on the summer brooding and population distribution of harlequin ducks on high mountain streams in the Gallatin and Custer National Forest. The surveys were completed by walking the stream banks of 53 outlined streams. A majority of the streams are located in four Forest Service Ranger Districts. The four ranger districts are the Big Timer, Livingston, Gardiner, and Bozeman that split the Gallatin National Forest. A summary and habitat description of each stream surveyed is given for each of the streams in the four districts covered. Potential habitat alterations and high recreation use problems are discussed. A total of five harlequin ducks were seen throughout this survey. Three adult males and two females were observed in the Boulder River drainage of the Big Timber Ranger District.
