Wild animals respond differently to nonconsumptive human activity and such variation depends on multiple factors. We explored the behaviors of Pseudois naynaur check for this species in other resources and recorded the distance of their responses in Suyu Kou National Forest Park, Helan Mountain, Ningxia Hui Autonomous Region. We categorized their behavioural responses as no response, vigilance and flight and recorded the response initiation distance. We compared distances according to disturbance source, group size, group type and sex. Our results showed that Pseudois naynaur showed stronger responses to humans than vehicles. The distance at which the subject of the group was vigilant in small group (group size less than three) was significantly more than that of larger groups (group size more than three). The flight initiation distance in small groups (less than five) was significantly more than bigger groups. The distance of no response behavior did not vary between all male, female or mixed groups. The distance of vigilance behavior when the subject of the group first encountered the disturbance in male groups was significantly greater for female and mix groups, flight initiation distance in female groups was greater than that of mixed groups. In the mixed group, no significant variation on sex was found among all three types of behaviors.
