Abstract

The sage thrasher, Oreoscontes montanus (Townsend), is a common bird that breeds throughout the sage brush areas of the Great Basin and from northern Arizona to southern Saskatchewan. Although it is a fairly common and conspicuous bird, almost nothing about its life history has been published. This study was conducted in central Washington during the spring and summer of 1969 and the spring and early summer of 1970. During the 1969 season, emphasis was placed on finding and tracing the phenologies of as many nests as possible in order to determine the timing of the nesting cycle. During the 1970 season emphasis was placed on the behavioral aspects of the breeding biology.
