Biology

Red-breasted Rosefinch is rare resident. It inhabits cliff and rock in nival and alpine zones at 2900-3400 m. In winter it occurs lower till to sub-alpine zone in rocks among juniper thickets, up to 2600 m. In Zailiyskiy Alatau near Bolshoye Almatinskoye lake in mid-May birds stay in pairs and their song was heard often. Displaying and copulation observed in 27 May 1965 and 24 June 1965. Nest is build by female, escorted by male, but not always. The first and one only known in the world nest was found in June 1967 at upper stream of Chukur river; nest located in wet chamber of crack in vertical cliff of north-eastern exposition, about 80 m from bottom and 40 m from top. It was obtained with help of twelve mountain-climbers, who only on third day after several attempts reached this crack. Nest was made from thin rootlets and dry grass mixed with hair. Clutch was contained from 4 pure white eggs rare spotted by dark-brown and light-brown mottles, speckles and hooks concentrated at blunt side of egg. Dimensions of eggs (n=3): 27.1-27.9 x 18.8-19.3 mm, weight 4.8, 4.9 and 5.0 g. (Other Carpodacus Rosefinches, nesting on bushes, have blue eggs). The female begins to incubate at last days of June probably. Only female incubates, male feed her. Near Bolshoye Almatinskoye lake three fledglings fed by female were observed 10 August 1975.
