Field signs. It is similar to the usual bullfinch, but in males breast, throat and side of head gray, and back - purely gray, strip on the wing light grey ([Syroechkovskiy], [Rogacheva], 1980). Weight 22-30 g, length of approximately 13-17 cm, wing 8,3-9,7 cm, spread of approximately 22-27 cm ([Ryabitsev], 2001). Propagation. East Siberian bird. Is found [P].[P]. [Sushkinym] (1914) on the nesting place from the East outskirts of the taiga of Minusinsk basin ([Mozharskaya] taiga). Rarely it winters in [Khakasii] and under Krasnoyarsk ([Tugarinov], 1927). In Western [Sayane] (Yenisey part) is noted as the being nested form of low-mountain pinus pumilas, slope [listvennichnikov] and mixed scaffolding in the river valleys (Sokolov and others, 1983: Petrov, [Rudkovskiy], 1985). In April 1981 even 1982 yr. is encountered in the valley of the Yenisey in the region of mouth r. Us On the Border the belts of larch and cedar taiga (height of approximately 1500 m) ([Syroechkovskiy], [Bezborodov], 1987). In eastern [Sayane] it is usual in the foothills in Krasnoyarsk, including in the posts ; prefer the riverside e[lovo]- fir scaffolding (Yudin, 1952; [Krutovskaya], 1958). On June 12, 1912. small flock of 10 birds is encountered BY [A].[YA]. [Tugarinovym] (1913) at upper timber line on khr. [Kuturchin]. In the wooded plain and [podtayge] it was not noted. In st. Of [kacha] under Krasnoyarsk of the gray bullfinches much less than usual, and in the southern taiga of lower [Priangarya] approximately equally ([Vladyshevskiy], it is oral. [soobshch]. [tsit] on [Rogacheva], 1988). In the average taiga in the Yenisey it nests everywhere, but approximately 2-3 times it is thinner frequent than the usual. Frequently the pairs of gray and usual bullfinches nest next. In northern Yenisey taiga both forms of bullfinches were also encountered together in the same relationship ([Rogacheva], 1988). Multiplication. Nest consists of two layers, external is made from the friable folded thin twigs of the rhododendron and other wood species, internal - from the rootlets and dry [stebelkov] of grasses. Chute is covered by thin rootlets and horse hair with the small admixture of fur. The height of nest 75-80, the diameter of chute 75, the depth of its 38 mm. from the earth nest little is noticeable, since its outer layer merges with the general background of branches ([Omelko], 1965). The participation of male in the building of nest and the hatching of laying and the duration of incubative period are unknown. In raising of nestlings participate both of parents ([Korelov] and others, 1974). Nourishment. The seeds of different plants serve as basic fodder. It in winter eats up also the kidneys of trees. Nestlings it brings up by seeds and invertebrates ([Korelov] and other, 1974). |
