Abstract: By the methods of fixed-spot observation,GPS positioning,plot sampling measurement and factor analysis,a comparative study was made on the feeding habitat of red-crowned and white-napped crane during their courtship period (from March to April) in Zhalong Nature Reserve in 2003 and 2004. The results showed that red-crowned crane preferred unique habitat for feed,mostly focused on water field (e.g.,reed marsh). During its selection of microhabitat,food factor played a crucial role,followed by concealment factor,water factor,and identification factor. The feeding habitat of white-napped crane was of diversification,and dry field,e.g.,Carex-marsh,farmland and burned field,was the priority. White-napped crane had a strict requirement in selecting feeding microhabitat,with “valid food” factor as the most important ingredient,and disturbance and water factors as the subordinate one.
