Abstract
The Qinghai-Tibet highway and railway cross desolate habitat at elevations of over 4600 m. We assess specie richness and abundance of ground-dwelling birds using strip transects located at a variety of altitudes perpendicular to this transportation corridor. Bird richness, bird abundance, and abundance of rufous-necked snowfinch, were higher adjacent to the roadway than further way. (A) Reprinted with permission from Elsevier.
