Field signs. The general tone of the top of body on the whole brown, nearer it is possible to examine the scaly figure, formed by the red borders of the feathers of back and covering of wing. White strip on the edge of tail is narrower and is dimmer. Mirror along the sides of neck they consist of the alternation of black and dove-coloured (not white) strips. Head and breast reddish-brown. On the outer autopilot dark gray painting goes to the external fan opaxal), the length of wing most frequently more than 18,5 cm. female only insignificantly differs from male in terms of the dimmer painting of breast. Is young even more faded, without the striped spots on the sides of neck. Weight 170-300 g, the length of body 33-35 cm, wing 17,5-22,0 cm, spread is wing 55-60 cm ([Ryabitsev], 2001). Cooing male low and deaf, slightly [urchashchee], is very more similar to cooing of [vyakhirya], but it is simpler on the structure of the repeated phrase. It most frequently consists of 4 styles, almost identical with respect to duration and loudness, usually after two higher on the tone they follow two lower. Is obtained something like to [khyykhyy]-[khuukhuu], . Sometimes entire phrase is pronounced on one note, either one of the styles sounds above or lower than remaining three. There are the styles of unequal duration, usually this the first or last in the phrase. Rarely before each 4- complex phrase there is as if aspiration, and then cooing sounds as e -[khyykhyy]-[khuukhuu], - is even more similar to cooing of [vyakhirya]. There is signal banging by wings ([Ryabitsev], 2001).
Places of inhabiting. Jack localities - different scaffolding near the free spaces, especially willingly settle [u] pour on ([Ryabitsev], 2001). Phenology. In the steppe regions they appear at the end April - beginning of May by small groups and one by one, predominantly fly in the morning hours. Autumnal migration begins gradually, from the [poslegnezdovykh] migrations, and it occurs in August - September, separate birds stay until October. They fly by small groups, being gathered by flocks at the places of feeding and on the overnight stays (on the trees) ([Ryabitsev], 2001). Multiplication. They live by single pairs, but sometimes adjacent nests are found in all in 10-15 m. male it designates the employment of territory by cooing and by current flight of the same type as in others show blue. Nest is built on the trees and on the bushes at the height of 1,5-5 m, sometimes to 15 m either entirely low- above the earth, on the stumps, [valezhinakh], the heaps of brushwood or completely on the earth. Nest is friable and is small, is constructed from the branches, the rootlets, the blades of grass. Cases occur the nesting in the old buildings of thrushes, forty, rooks and other birds. In laying of 2 white eggs with the size of 30-37 X of 22-26 mm. they hatch on the turn, but female is more, and male feeds it, bringing food in the goiter. The hatching bird allows to approach man close, then it is torn away and flies away, or it leaves nest previously. At the end hatchings and after hatching of nestlings frequently are removed from the nest, pretending by injured. Duration of the incubation of 14-15 days. Nestlings in the yellow to down, with the very dark (brown or black) skin. Two week nestlings can come out from the nest to the adjacent branches, they fly approximately at the monthly age, but flutter if necessary they can and it is earlier. If the first nest perishes they, as a rule, nest repeatedly ([Ryabitsev], 2001). Nourishment. They feed by the seeds of cultural and many wild plants, and cedar it is nut up to the wing nuts of ash. Fodder is gathered on the earth, preferring to other places of the curb of roads, fields and other free spaces. They eat berries, worms, insects, small snails ([Ryabitsev], 2001). |
Propagation. the Southern- east Siberian form, which is widely encountered in southern half of average Siberia. In proportion to the mastery of taiga by man and the disturbance of its enclosed, uniform standing timber [rasprostranyabshchiysya] to the north. Along the Yenisey the turtle dove is traced on the nesting place to s. Verkhne-Imbatskoye (63o 10 ' N, the northern part of the subzone of average taiga), is encountered also in sett. [Baklanikha] (64o 25 ' N) in the typical northern taiga ([Rogacheva], [Vakhrushev], 1983).[Back] |
