Abstract: The interspecific relationship among Nycticorax nycticorax,Egretta eulophotes, Egretta garzetta, Bubulus ibis and Ardeola bacchus during breeding period was analysed.Inner and interspecific coordinate evolution and competition relationships in the mixed population of herons were discussed in aspects of vertical and level distribution, time_difference of breeding and feeding, feeding structure and feeding place differentiation. The basic regulations were illustrated.
