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. Study on the food habits was important for us to manage herons and preserve biodiversity.展开更多
On 11 June 2001, at the hinterland of Taklaimakan Desert ( 39°10`N ,83°40`E, 1100 m a.s.l.) in Xinjiang, west China, we observed one Chinese pond heron (Ardeola bacchus) in a small pond with reed (Phragmites...On 11 June 2001, at the hinterland of Taklaimakan Desert ( 39°10`N ,83°40`E, 1100 m a.s.l.) in Xinjiang, west China, we observed one Chinese pond heron (Ardeola bacchus) in a small pond with reed (Phragmites communis) near the Tarim Desert Highway . It may be migrating from south to north. We took some photos to record it. It is an unmistakable species: its head and neck are reddish brown, back is slaty blue, and white wings are distinctive in flight. It is a new species record in Xinjiang, an extremely arid region in Central Asia. According to Cheng(1987), the west and southwest distribution boundaries of this species in China are Qinghai Lake and south Xizang respectively. Chinese Pond Herons inhabit the wetlands generally. Most of the wetlands in the Taklamakan Desert exist in a small area (about 200 m 2 in general), and the interval distance between the wetlands is mostly about 250 km (e.g. the distance between the Tarim, Niya and Hotan rivers). Therefore the apperance of the Chinese Pond Heron at the hinterland of Taklamakan Desert, the largest mobile desert in China, is really a surprise event.展开更多
