Sooty grouse are popular gamebirds in Oregon, but they're cryptic and tough to keep track of unless it's mating season and the male grouse are hooting. Starting in spring, biologists from all over western Oregon head up into the mountains driving forest service roads or logging roads to listen for hooting grouse. A recent partnership between Oregon State University and ODFW seeks to improve how we collect data about sooty grouse by utilizing acoustic audio recorders to better track when grouse are and are not hooting.  Rated moderately nerdy
