(1987) Perdix hodgsoniae sifanica.
THE KANSU PARTRIDGE.
Perdix sifanica Przevalsky, Mongol. Shan. Tang.,ii, p. 124 (1876) (Kansu),
Vernacular names. Sakpa (E. Tibet).
Description. Similar to P. ft. hodgsoniae but much less richly coloured, the blue-grey tint on the upper parts is either absent altogether or is confined to the upper back or interscapulars; the lower parts also are duller and there is less chestnut on the flanks and the sides of the breast; the black on the cheeks is also less in extent than in P. h. hodgsoniae and never meets below the throat.
Colours of soft parts as in the preceding race. Measurements. Wing 140 to 153 mm.
Distribution. North-East Tibet, Nanschan, Koko Nor to Setchuan; Bailey found it in suitable places from Setang to Dokeng on the Upper Irrawaddy Valley.
Nidification. Przevalsky found young birds in August but in May the hens had only commenced to lay. Some clutches of eggs taken between Chiamdo and Batang in extreme East of Tibet were found some time in early July and are exactly like those of the Tibetan Partridge. The clutches contained five to eight eggs.
Habits. Przevalsky found this Partridge between 12,000 to 17,000 feet and records it also on the plateaux at about 10,000 feet elevation ; Bailey obtained it between 12,500 and 15,000 feet. It seems to haunt rhododendron-thickets as well as the open plateaux and grass-plains.
