Observations on the Griffon Vulture Gyps fulvus (Hablizl, 1783) located in Yazılı Kanyon (Isparta)

The aim of this study performed in yazılı kanyon (isparta province) between october 2007 and july 2008 was to define the number of individual sand mobility of griffon vulture (gyps fulvus). we observed 12 individuals in the area during pre-breeding and courtship periods. the number of individuals changed daily and seasonally depending on climatic, geographic and anthropological factors. only one pair showed breeding activity. the nesting and roosting areas include limestone mountains (800 m) with granite. feeding activities were observed more often in the breeding season than other times because parents had to find food materials for their chick. but, these activities were decreased significantly after breeding season.
