The strange thing was, these birds were puffing up the bulbous air sacs on their chests, their songs calling out to nearby hens, right in the middle of a giant burn scar. “You’ll see these males displaying out in a completely burned, barren landscape. And they seem to be able to handle it,” says Michael Schroeder, who’s been working on sage grouse issues for the Washington Department of Fish and Wildlife for nearly 30 years.
