Distribution

Hodgson's Rosy Finch breeds in highlands of Tien Shan eastward from Pskem and Ugam, in Dzhungarskiy Alatau, Saur and in Southwest Altai (near Rakhmanovskiye springs too). Probably lives in Tarbagatay. On dispersal and in winter Hodgson's Rosy Finch very rarely occurs in foothills and on adjacent plains (near Semipalatinsk at December 21 1920; in Taldykorgan area; in Chulak Mts. Kzylaus gorge at March 28 1949, in Almaty; and near Dzhabagly settlement at April 08 1960).

Biology

Hodgson's Rosy Finch is abundant, in places rare resident. It inhabits sup-alpine belt in highlands, from upper board of forest belt up to alpine meadows with cliffs and stone scattering, at 2350-3500 m in Tien Shan. At breeding areas singing males observed in May. Hodgson's Rosy Finch breeds in separate pairs, at 15-100 m from each other. Pairs are formed from March till May. Nest is built in ground hole, under stone (rarely between stones or in cliff crack) mainly by female for 7-10 days. Nest is built from dry grass and rootlets and is lined with hair and feathers. Clutches of 3-6 eggs founded from end of May to mid-July, mainly in June. Only female incubates for about two weeks, in this time male feed her. Both parents feed juveniles, which fledge at age 15-19 days old, it happens from early July to mid-August. In breeding time, Hodgson's Rosy Finches search food by groups, sometimes up to several dozens birds. In autumn and in winter Hodgson's Rosy Finch lives in flocks at altitude lower than breeding areas, but on plains almost never descends.
