Comparison on Activity Rhymes Between Two Sympatric Pheasants Chrysolophus pictus and Tragopan temminckii and Their Response to Human Disturbance
In order to reveal the similarities and differences in the activity rhythms of the related species of Chrysolophus pictus and Tragopan temminckii in the same domain,and their changes under human interference,this study used the long-term infrared camera monitoring data from 2017 to 2020 and studied the diurnal rhythms of C.pictus and T.temminckii by nuclear density analysis method and overlapping model.Results showed that:(1)Both pheasants were mainly active in the morning and dusk.Comparing with the breeding season(Δ=0.874,P>0.05)and rainy season(Δ=Compared with 0.869,P>0.05),the overlap coefficients of activity rhythms of two pheasants in non-breeding season(Δ=0.862,P>0.05)and less rainy season(Δ=0.914,P>0.05)were relatively high,but the activity peaks were not the same.(2)Chrysolophus pictus showed obvious avoidance behavior in human activities(Δ=0.787,P<0.05)and livestock(Δ=0.831,P<0.05),while T.temminckii had a smaller degree of avoidance of domestic animals(Δ=0.878,P>0.05).Although the activity rhythms of the two pheasants distributed in the same domain overlap greatly,there were still seasonal differences in activity rhythms,and the response to human disturbance was also different.This study can provide a basis for further exploring the behavioral ecology and species coexistence of the two pheasants.
