This undated file photo provided by Washington State University shows an endangered pygmy rabbit in the wild in eastern Washington state. The U.S. Fish and Wildlife Service improperly failed to make a decision about protecting the rare pygmy rabbit in eight Western states, according to a lawsuit filed in federal court by an environmental group. Western Watersheds Project’s lawsuit, which was filed last week, wants the agency to make a decision on whether to grant endangered species protection to the tiny rabbits. Courts had previously demanded the decision, which is long overdue. (AP Photo/Washington State University, Len Zoeli, File)
