Abstract: In the spring of 1987~1992,studies on the migration ecology and biological characterstics of the main species or raptors had been conducted at their main roosting sites (Qingdao,Changdao of Shangdong Province,Laotieshan of Dalian City,Liaoning Province).According to the research,the north migrating raptors pass through the roosting sites from early March to late June.The migrating peak period is from late March to early May.Through the analysis and statistics of climate,it has shown that the massive migration of raptors in spring will be influenced intensively by climate.The disastrous climatic conditions in early spring will do harm to the overwintering and migrating raptors in this area.The best weather for raptor migration is on sunny days with south wind of 3~5 scale.
