From the Introduction: "In this paper, we describe the dispersal behavior of northern spotted owls based on relocations of banded owls and radio-marked owls in Oregon and Washington. Our specific objectives were to (1) investigate sexual differences in dispersal, (2) describe the chronology of natal dispersal, (3) describe integration of young owls into the territorial population, (4) describe effects of landscape features on dispersal, (5) describe social factors associated with breeding dispersal, (6) determine if estimates of dispersal parameters differed between banded and radio-marked owls, and (7) determine if dispersal distance was positively correlated with the age when owls first nested. We discuss how our results fit with previous studies of dispersal in birds and with some of the hypotheses that have been suggested regarding causes of dispersal. We also discuss our findings in the context of current management plans for the owl, and we provide suggestions that modelers might use to develop more realistic spatial simulation models for spotted owls."
