Abstract

During 1995-2004, we studied the nest site selection of the Chinese grouse Bonasa sewerzowi at Lianhuashan, Gansu, China. Of the 103 nests that we found, 56% were at the base of deciduous trees, mainly willow Salix spp. and birch Betula utilis, and 40% were at the base of coniferous trees. The Chinese grouse favoured northern and eastern slopes with steepness of 0-45°, averaging 15.5 ± 11.2° (SE; N  =  97); 88% of nest sites were on slopes of < 30°. The average cover around the nest was 50.8 ± 20.3% (SE; N  =  86). The degree to which the female was covered at successful nests was 51.4 ± 19.9% (SE; N  =  45), which was not different from that of unsuccessful nests (43.1 ± 19.1% (SE); N  =  17). Chinese grouse preferred to nest in coniferous and coniferous-deciduous mixed forests at sites with fewer trees and denser shrubs, compared with the available vegetation. Females nested on average 154.2 ± 109.0 m (SE; N  =  19) from the previous year's nest. Compared with the hazel grouse B. bonasia, the Chinese grouse showed a greater preference for nesting at the base of trees or stems.
