In north-central Oregon, Red-tailed Hawks (Buteojamaicensis) exhibited a high degree of stability in territory occupancy and territorial boundaries over a 10-yr period. Long-term repro- ductive success varied markedly among territories and was correlated primarily with the dispersion and density of perches used as foraging sites and secondarily with the abundance of ground squirrels, principally the Belding's Ground Squirrel (Spermophilus beldingi). These results imply that prey availability is… Expand
