Field signs. Stroynaya bird (17 g weight) with a long tail, which constantly shake. Back in males olive-green, wings and tail burovato-gray bottom bright yellow, head of gray with bright Brovko. The females top faint, whitish-yellow bottom. Young burovaty top, bottom ohristy, on the sides of the throat and zobe black and brown pestriny. The voice is similar to the voice of the white wagtail, but more vocal. Prisazhivaetsya at the top of tall grass (Syroechkovsky, Rogacheva, 1980).  Distribution. Widespread Palaearctic bird marsh grass with bushes. In the south central Siberia pervasive and usually on raw meadows and humid parts of the steppe and forest. In the mountain does not go, appears only occasionally in the foothills of meadow along the river. PP Sushkin (1914) pointed out to her and Usinskoy basin. The raw meadows Krasnoyarsk, Achinsk and Kanskoy forest usually (nesting numbers 1,2-7,1 individuals / km 2) (Kim, 1977). In continuous taiga rare, but the nest continuously, especially in the valleys of large rivers. In the southern taiga subzone at the Yenisey in the riverine meadows and villages in the yellow wagtail for nesting is not seen, they appear from mid-July from the vyvodkami (an average of 6 and 22 individuals / km 2); nest, probably in the marshes and meadow outside the valley Yenisei. In the middle taiga in the valley on the Yenisei nesting rare; slightly higher margins on its low-lying swamps and transitional deep in the boreal forest in the area of peace becomes a regular or large in late July, when the Bank Yenisei move podrosshie vyvodki of "Depth". In the northern taiga numbers of yellow wagtail increases; margins than the open marsh, it starts in a greater number meet in floodplains side rivers in the southern subzone (Baklaniha, 64 o 25's. Rd.) Nesting numbers in 1977 on the flood plain meadows -- 47 and the transitional swamps 26 individuals / km 2 (Rogacheva, Vakhrushev, 1983).
In prieniseyskoy and depth of left-bank large forest type. Jacks on swamps and in damp bush (ernikovyh) bush. In the southern eniseyskoy forest (Ust-Hantayka, 68 o 15's. Rd.) Nesting numbers in 1977 stood at ernikovyh tundra wetlands with 256 species / km 2 in the flood plain Yenisei - 18 in woodland - 0. In a typical forest eniseyskoy (Nikolskoye, 69 o N), respectively, equal to the number 77 and 8, and woodlands - 16 special / km 2 (Rogacheva et al, 1983). In the upper river. Turuhan yellow wagtail dominated in all areas ernikovyh tundra in the southern district of Soviet Lakes. In the mountains Putorana from Norilsk lakes place of habitual, increasingly rare. In Evenkia almost non-existent, at least in the valleys of large rivers (Podkamennaya and Lower Tunguska) in the middle and northern taiga, but usually, or numerous in the lake basins, rivers and near the village of Evenkia Northern and Southern Taimyr (extreme northern taiga and the forest ) (Volkov, 1987; Rogacheva, Syroechkovsky, 1969); so, the Village. Khatanga (72 o N) nesting numbers in 1982 reached 371, and in the surrounding woodlands with thickets of larch ernika - 42 individuals / km 2 (Volkov, 1987). In subzone bush tundra (mouth Yenisei, 70 o N) in the same biotopes favorite - ernikah, on the outskirts of tundra marshes - the yellow wagtail was limited to conventional (1-7 individuals / km 2) (Ravkin, Gleyh, 1981). In subzone typical tundra, as a rule, they do not exist as a species, while AJ Tugarinov met her on the mouth of the river. Deep (72 o 20's. Rd.) (Rogacheva, 1988). Habitats. Izlyublennye habitats - meadows and grassy marshes, pasture with a few bushes and the trees, Bank of raw water in a wide range of latitudes. Nest to the wet fields in the wet steppe in the bush tundra with swamps and lakes. For characterized by uneven distribution, where similar habitats in places not inhabited, and places are formed dense settlements, where the couple resides in a pair of dozens - hundreds of meters (Ryabitsev, 2001). Phenology. The Atlanta arrives in the first half of May, egg laying - May 28 - June 7, by the end of June, the young fly from the nest, all the birds fly away to the south in mid-September (Tugarinov, Buturlin, 1911; Yudin, 1952). Reproduction. Jacks suit on the ground under the cover of grass, kochek, shrubs or even dry cows "cakes". This suite of fine herbs, roots and other plant material, for lining the use of wool wide variety of animals, rarely - feathers or other soft material. In laying 3-8, usually 5-6 eggs. Fon shell white or with a soft touch - pinkish, brown, gray, etc., opyatnenie soft ohristoe, burovatoe, gray, consists of a shallow thick sypi, which usually closes the background, may be quite invisible rash and eggs seem to be uniform. The size of eggs 16-21 x 11-16 mm. Female nasizhivaet with otkladki eggs last 13-14 days, is anxious about his food. Male busy tracking of predators and protection of the territory, chicks nurse together. Do chicks down on the head and back with sand, light ohristogo or brownish-yellow color, mouth red-orange, orange or dark yellow, klyuvnye rollers light yellow. The normal length of stay in the nest 11-14 days (Ryabitsev, 2001). Power supply - small invertebrates (spiders, Vesnjanka, Flies, etc.) (Syroechkovsky, Rogacheva, 1980).
