Abstract: We conducted an experiment of environmental enrichment and feeding enrichment on the captive browneared pheasant (Crossoptilon mantchuricum) in Pangquangou National Nature Reserve, Shanxi Province from April to May, 2010 and from December, 2010 to August, 2011. In order to test the effects of different enrichments on the captive browneared pheasant, scan sampling, focal sampling and all occurrence sampling methods were used to observe the behaviors of these pheasants. The results showed that the exploring behaviors of both environmental enrichment and feeding enrichment groups were significantly lower than that of the control group. Foragingrelated behavior had no obvious pattern at different enrichment stages. The performance intensities of the abnormal behavior in the two enrichment groups were lower than that of the control group. Taking the whole enrichment stage into account, the timeallocation percentages of foraging, locomotive and breeding behaviors in the environmental enrichment group were significantly higher than those of the control group. However, the timeallocation percentages of vigilant behavior and abnormal behavior were significantly lower than those of the control group. The timeallocation percentages of foraging behavior and resting behavior in the feeding enrichment group were extremely significantly higher than those of the control group, while the percentages of vigilant and abnormal behaviors were significantly lower than those of the control group. With the progress of the enrichment program, the behavior diversity increased gradually in the environmental enrichment group, and initially increased and then reduced in the feeding enrichment group, while reduced gradually in the control group.
