摘要: 有关灰weilingMotacilla cincerea robusta的生态资料,至今报导较少。作者从1962年以来在长白山工作期间,就便对灰weiling的生态作了一些零星的观察与记载,1974年和1978年又作了较为详细的观察。现将资料整理出来,以供有关方面参考。Abstract: The Eastern Grey Wagtail (Motacilla cinerea robusta) is one of the commonest Summer migratory birds in the region of the river-side in Changbai shan,Jilin Province.They usually arrive the said mountain at the beginning of April to the middle of April,and remain there until the end of September to the beginning of October.
