Abstract:Winter movement and social behavior of Chinese Grouse ( Bonasa sewerzowi ) were studied at Lianhuashan Natural Reserve, northwest China from 1995 to 2009. According to radio-tracking data from 25 male Chinese Grouse, their home ranges in winter ranged from 6.0 ± 1.6 ha ( n = 9) to 16.0 ± 2.6 ha ( n = 10). Most females and all the yearlings moved from breeding areas and formed mixed-sex flocks. However, males adopted one of three social behaviors and movement patterns, including: staying in the territory, moving to the winter flocking area, or wandering between the spring territory and the wintering area. In order to find out which factors influence male social behavior, we used multinomial logistic regression and AIC model selection to compare the habitat characteristics of male Chinese Grouse breeding territories. Modeling results indicated that food, cover, topography, and future breeding opportunity were the main variables determining social behavior in winter.
