Annulated turtle dove Streptopelia of decaocto (Frivaldszky, of 1838)

Field signs. It is less and much more ordered than the dove-coloured pigeon, approximately usual turtle dove. The top of body and folded is wing sandy color, head and breast greyish- red, with the pleasant pink nuance. From usual and large turtle doves differs in terms of the absence of dark speckles on the spin and covering of wing, the top single-tone, [podkrylya] bright, on the neck from behind elegant narrow black semiring in the white rim. White color on the tail occupies near or more than third area of autopilots, but it does not appear only by edge. There is no distinct sexual dimorphism, females are painted only more faded. The young do not have pink nuance, instead of it ocherous attack on the breast and the back, there is no black semiring, it is less than the white on the tail. Weight 135-250 g, length 31-33, wing 17,3 - 18,8, the spread of 47-55 cm ([Ryabitsev], 2001). Cooing male rather deaf and monotonic, consists of the repetition of trisyllabic cry with the stress on the average style: Hu-[khUu]- Hu , instead of the last style sometimes follows their entire series: Hu -[khUu]-[khukhukhukhu] , and then entire phrase reminds of deaf laughter. In the shortened form cooing and other similar sounds can be heard, also, in other, not current situations ([Ryabitsev], 2001). Propagation. For the elongation [KHKH] v. occurs the rapid settling of form from the initial area - Yu. of Asia. To the middle 1970- X of years the form mastered the large part of Europe, to the north to Scandinavia, Saint Petersburg, Moscow, Volgograd, the south of Kazakhstan. At the beginning the 1990's years annulated turtle dove as the being nested form is already registered in Bashkirya and in the south of the Chelyabinsk province ([Ryabitsev], 2001). |
