Field signs. Melky, with the sparrow, kulichok with nedlinnymi legs and beak. Top pock-marked, fox, white bottom. Spring throat and goiter bright red. In the winter in nature almost indistinguishable from a Whooper Swan. Young rust under the neck, across the goitre, is a series of brown pestrin. Bespokoyny Creek - chlek-chlek, when current flight - particularly cluck.  Distribution. Pesochnik-krasnosheyka available from the Taimyr east to the eastern and southern coasts of Chukotka p-ova Anadyr and mouth (Stepanyan, 1990). Within Prieniseyskoy Siberia distribute it insufficiently studied. In 1966, AA Vinokurov (1971) for the first time found krasnosheyku for nesting near the village. Ust-Tareya (two pairs). Young and nerazmnozhavshihsya birds seen in summer and west. So, AJ Tugarinov gotten 28 Jul, 1908 adult female in poslegnezdovoy molting gaggle of Whooper Swan at the mouth of the river. Deep in the Gulf Eniseyskom (Tugarinov, Buturlin, 1911). There is a series of meetings in the north-western Taimyr, in the vicinity of Dickson and at the mouth of the river. Uboynoy (Vronsky, 1986). VA Zyryanov and VV Larin (1983) at the Spring flying in the mountains Putorana said in gaggle Whooper Swan and 10% sandpiper-krasnosheek. Found in East Taimyr: under 76 o 40 'N, at Cape B. Cargo, at the mouth of the river. Most Balahnya (Pleske, 1928; Vinokurov, 1971), which reliably established and nesting (Morozov, Tomkovich, 1984). Span of the sandpiper states in southern Siberia Prieniseyskoy (Tolchin, Pyzhyanov, 1980; Savchenko, 1986).
Habitats. The most comprehensive analysis of zonal and biotopicheskogo spread of sandpiper-krasnosheyki, including the western part of the range, a VV Morozov and PS Tomkovichem (1984). According to these authors, the review clearly a kind of attachment to the Tundra mountain and foothill landscapes, which he occupies mesophilic tundra various options with a significant participation of the Greens, less sphagnum moss. This avoids the sandpiper pushitsevyh kochkarnikovyh tundra at the broad valleys and plumes sopok than, perhaps, explains the fragmentation of its habitat. Phenology. In place of nesting arrives in late May - early June (Kozlov, 1962). After an extensive area of taiga, migration, probably, is predominantly transit, to water bodies and forest-steppe zones krasnosheyki stop and feed on the banks of ponds with varying degrees of salinity. In contrast to the long-sandpiper krasnosheyka prefers open ilistye shoals or sand bank. Span is stretched and fall more evident than in spring. At that time, meet as adults, and fingerlings, the last notable prevail. Sandpiper-krasnosheyki migrating through the south Prieniseyskoy Siberia, winter in North-Western Australia (received two refund of Okol'covannaja birds). Reproduction. According to the VV Morozov, PS Tomkovicha (1984), sandpiper-krasnosheyki beginning to build individual territories immediately or within a few (up to eight) days after the first birds. Some observations made by these authors suggest that a small portion of krasnosheek arrives to nesting sites in pairs, others formed later in the territories occupied by males. In-site habitat pair of comfortable nest, nasizhivayut immure both parents. The nest is a small, I ISU among grassy vegetation or moss, usually with a good lining sedgy, osier or birch leaves (Kozlov, 1962). Complete masonry composed of four eggs melkokrapchatoy reddish-brown color. At the time of hatching chicks females tend to leave the area of reproduction, and males remain with vyvodkami to recovery chicks on the wing (Morozov, Tomkovich, 1986). Meals poorly studied, mainly insects and their larvae: mosquitoes, weevils, ground beetles, Hymenoptera (Kozlov, 1962). Number. Recent data on the number of species in the western part of the range available. In southern Siberia Prieniseyskoy in stopping and concentration sandpiper (genus Calidris) krasnosheyki according to the Web otlovov networks do not exceed 5% of the total number of birds in this group. Thus, in Khakassia of 1856 caught sandpiper krasnosheek was 73 species, in Tuva from 4646 - 84 respectively. Assessing the size ratio and the proportion of the type shown on the otlovov since the fall Attire, even with close consideration krasnosheyki virtually indistinguishable from Whooper Swan, which is a normal span species in the province. Since all sandpiper track evenly, without distinction, you can confidently say that krasnosheyka small, but regularly occurring species region (Syroechkovsky et al, 2000). On the waters of the Krasnoyarsk Territory (Lake Intikol, Salbat, Greater and Lesser Kosogol etc.) kulichki stop these small groups, often kept in mixed flocks with other sandpiper. Reductions in size over the past 10 years are not observed, comparing the data with earlier observations impossible because of their epizodichnosti and lack of quantification (Savchenko, 1997). Details VA Tolchina and SV Pyzhyanova (1980) on the massive flying krasnosheek in Minusinsk Basin is not confirmed by subsequent studies (Syroechkovsky et al, 2000). Measures of protection. Like other Kulikov, protected by hunting laws. Species included in the list of Russian-Indian convention on the protection of migratory birds (1984). It should be the preservation of the entire Eniseyskomu meridian unique wetlands that are essential and traditional stops gemiarkticheskih species (Syroechkovsky et al, 2000). References. |
