Habitat selection of the Tibetan Snow Cock in the spring in Lhasa

Abstract

The habitat selection of Tibetan Snow Cocks in shrub vegetation was investigated in Lhasa, Tibet, China, between March and April, 2005. Fourteen parameters were measured. These include altitude, slope, slope aspect, slope position, vegetation cover, plant type and other environmental parameters. Results show that Snow Cocks favor foraging in areas where vegetation cover was small and close to the residents’ houses. Supplementary food supplied by humans has caused Snow Cocks to decrease their foraging range. Snow Cocks also favor roosting in areas with low vegetation, sparse grass, short grass, large rocks and close to houses. The Snow Cocks’ activity in the study areas show a close relationship with human activities.
