Based on food habits, food diversity and similarity were compared. The nestlings of Chinese pond heron were fed with fish and insects, those of little egret were given with fish and shrimps, however, those of black-crowned night heron were brought up with fish and amphibians. Of the diets of the three species, nestling Chinese posnd heron had the widest one, nestling black-crowned night heron had the narrowest one. Nestling Chinese pond heron had the highest preference to insects, but nestling little egret and nestling black-crowned night heron had the highest preference to fish. Similarity of food between nestling little egret and nestling black-crowned night heron was the highest, but was the lowest between Chinese pond heron and black-crowned night heron.
