Abstract
We used marine radar to study nocturnal bird migration at the Vansycle Ridge and Stateline wind energy projects in northeastern Oregon and southwestern Washington during fall 2000, spring 2001, and fall 2001. Our study was designed to monitor waterfowl, shorebird, and passerine movements during spring migration and passering movements during fall migration. Understanding the basic components of nocturnal bird migration in specific locations can help site future development projects in a manner that will help conserve nocturnal migrants.
