Red-tailed Hawk Dispersal and Migration

In 1999 a study was undertaken to test the hypothesis that events occurring during migration and on wintering areas are correlated with low productivity of a population of Red-tailed Hawks (Buteo jamaicensis) from Jackson Hole, Wyoming. We describe the migration routes, length of migration, duration of migration, weather influences on migration, and make an environmental assessment of wintering areas. Additional research objectives are to quantify factors affecting Red-tailed Hawk productivity, specifically; prey abundance, egg and nestling predation, influences of weather, nest site competition, parasite levels, habitat selection, and human disturbance.
