説明

Data on the breeding ecology of Tibetan Partridges (Perdix hodgsoniae) were collected in shrub environments near Lhasa, Tibet, during 1999-2001. Partridge flocks broke up in mid-March and individuals typically formed socially monogamous pair bonds. During daily activities the both members of the pair were close to each other, with 73.5% of observed individual distances less than 2m. The egg-laying period extended from late May to late June. Average egg size was 16.1 (±SE=0.2) g in mass and 39.2 (±0.1)×28.1(±0.1) mm in dimension. Average clutch size was 8.3 (±0.8, range 5-12) The partridge produced larger eggs and smaller clutches than its two congener species, Grey Partridge (P. perdix) and Daurian Partridge (P. dauuricae). Incubation lasted about 23 days, and 44.4% of clutches successfully hatched. Vegetation characteristics were the most important determinants of partridge nest-site choice, with patches of low, sparse, and secondary cover being preferred. Nest-sites were also significantly closer to paths than random sites.
