Do predators limit grouse populations?
Predation can play a role in limiting grouse populations, but it is more likely that the problem is poor habitat quality that makes birds, their nests, and broods more vulnerable to predation. Grouse have evolved behaviors and reproductive strategies to cope with predation, but in highly fragmented landscapes predators may be more efficient in finding grouse and their nests. This is particularly true for nest predators such as raccoons, skunks, and opossums. In areas with poor habitat quality, such as low stem densities or poor overhead cover, grouse and chicks may be more vulnerable to avian predators such as hawks and owls. Again, it is declining habitat quantity and quality on both a local and landscape scale that is increasing grouse vulnerability to predation, not simply higher predator populations. Large predators, such as coyotes, may be impacting game species on a local scale, but it is unclear whether they are affecting populations in large regions of New York or statewide. DE
