Sex-specific seasonal variation in home range size in a sedentary avian predator.

ABSTRACT: Spatial ecology of species is determined by the interplay of various social and demographic factors. Variation in utilisation of space may also reduce the conflict between individuals competing for the same resources. We simultaneously evaluated the effects of sex, territoriality and reproductive performance on the space use of the Eurasian goshawk, Accipiter gentilis, by analysing the home range sizes of 25 individuals across various stages of the annual cycle for up to 7 years. The mean annual home range (90% autocorrelated kernel density estimate) of territorial goshawks was slightly smaller than that of non-territorial hawks, and the ranges of successful birds tended to be smaller than those of non-successful territorial goshawks. The median home range of territorial females (295 km
