Predator kills of sage-grouse are difficult to assign to a perpetrator, unless witnessed. This sage-grouse was killed by an avian predator or raptor. Raptors pick at the meat and don’t crush the bones. Sage-grouse have always evolved with predators. However, predators can have an advantage if cover components are reduced.
Most predators specialize in taking either eggs, young, or adults. Some, however, are capable of taking birds at all life stages.
