Highlights ► We study birds’ response to human approach along different road effect levels. ► This study was done along the Qinghai–Tibet Highway and Railway. ► We use alert distance and flight initiation distance to evaluate road effects. ► Birds have shorter alert distance and flight initiation distance near roads. ► Qinghai–Tibet Highway and Railway affect the bird’s vigilance behavior.
Abstract We used alert distance and flight initiation distance to evaluate the effects of the Qinghai–Tibet Railway and Highway on snowfinches’ responses to human encroachment. Road effect was divided into those associated with villages as high disturbance, area between Qinghai–Tibet Railway and Qinghai–Tibet Highway as medium and other areas away from roads as low. The result showed that the alert distance and flight initiation distance of snowfinches decreased significantly with increasing road effects, which indicated the Qinghai–Tibet Railway and Highway significantly affected the bird’s vigilance behavior.
