Energy development affects populations of sagebrush songbirds in Wyoming
Abstract Oil and natural gas development in the Intermountain West region of North America has expanded over the last 2 decades, primarily within sagebrush dominated landscapes. Although the effects of energy development on high‐profile game species such as the greater sage‐grouse ( Centrocercus uro...
