3: 2015). The Sagebrush Sparrow is a migratory sagebrush obligate songbird that nests in sagebrush shrublands. The Sagebrush Sparrow has a global population of 4.7 million birds and its breeding range covers more than 1 million square kilometers (Figure 3). The species shares much of its breeding range with the greater sage-grouse: 43% of the Sagebrush Sparrow’s range overlaps that of the grouse (Table 1). The Sagebrush Sparrow is listed as a species of concern in three western states: Wyoming, Montana, and Washington (Table 2). Like many sagebrush songbirds, the Sagebrush Sparrow is declining throughout its range (the Sagebrush Sparrow analysis includes data for the Bell’s Sparrow (Amphispiza which was split from the Sagebrush Sparrow in belli) 2013.) The species is declining most rapidly in the Southern Rockies/Colorado Plateau region and the northern Great Basin in southeastern Oregon and southern Idaho (Table 6, Figure 4). At the state level, the population decline is greatest in Idaho, Oregon, and Colorado, where the species is estimated to be losing more than four percent of its population annually. The data from Idaho and Colorado, however, contain data deficiencies that may affect the accuracy of the trend estimate. The 2012 PIF plan (Rosenberg et al. 2016) classified the Sagebrush Sparrow’s breeding threats as a 3, denoting a slight to moderate decline in the future suitability of its breeding conditions (Panjabi et al. 2012). 4: (1966-2013)
