Abstract： The remiges， rectrices， contour feathers and downy feather of Black Drongo（Dicrurus macrocercus） and Chinese Blackbird（Turdus mandarinus） were selected as research objects， and their microstructures were observed and compared by scanning electron microscope（SEM）. that the identification criteria for the two bird species are as follows： （1） For remiges， the length of base handle of distal barbule， the number of hooked barbule， the number of cilia， the sum of the hooked barbule and cilia， the number of ventral tooth and the distance between barbules; （2） For rectrices， the length of base handle of distal barbule， the number of hooked barbule， the number of cilia， the sum of the hooked barbule and cilia and the distance between barbules; （3） For contour， the indicators such as the length of base handle of distal barbule， the number of cilia， and the distance between barbules; （4） For downy feather， nodular diameter， distance between nodules， length of base handle and distance between barbules.
