PPxh1a Breeding range Brewer's sparrows breed regularly south of Penticton to the U.S. border on the west side of the Okanagan valley, and in the Similkameen valley south of Keremeos. Singing males have also been observed near the confluence of the Fraser and Chilcotin Rivers, but it is unknown whether these represent breeding birds or unsuccessful outliers. Most breeding territories in the South Okanagan occur in fair and good range condition, but it is unclear if this represents selection of mid-successional plant communties or is a reflection of available habitat. Grasslands with sparse sagebrush offer few sites for the construction of secure nests. Selected references Dobler, F.C. 1990.
