Field signs. The size from about gardens and barsuchka, with a monotone riding without pestrin and dark bands. Top of olive-brown, with a light "warm" ohristym bloom and a few fox poyasnitsey, whitish bottom, with clear ohristym or sulfur-yellow tinge. Over all, like a garden, as well as the Indian kamyshovok. The best of these kinds of differences - a clear light on dark ohristye kaemki makhovaya plumes, particularly noticeable in the tertiary, a bright ring around the eye stands out more clearly than light eyebrow, legs bright, ohristye. Male and female indistinguishable. Weight 11-16 g, length about 13 cm wing 6,3-7,2 cm, the magnitude of 18-21 cm (Ryabitsev, 2001). Song is very diverse and beautiful, has taken over a lot of other kinds of signals and elements of songs. Slitnost characteristic elements and haste songs than it is different from the songs garden kamyshovki. Over all, like a song trostnikovoy kamyshovki, but loud and visible. Song does not have a specific duration and watches most of current activity - at zoryah and at night - may sound without breaks for many minutes. Day sing more sluggish and more frequent breaks. No current flight, with the singing dog is usually sitting on the serving line bush beak widely disclosed, throat high-blown, sometimes bird shakes entire body, reveals the tail and pulled it from side to side, sharply raises and lowers the wings. Not so shy and secretive, with singing, like many other kamyshovki. By midsummer night sing little or very silent, the daily activity of singing, too, declines, the longest (until mid-July) you can hear on zoryah. Alarms - "check", "black", treskuchee "cherrrr" or "chrrrrr", a combination of these cries (Ryabitsev, 2001). Distribution. European appearance bushes and vysokotravya, has been observed in Central Siberia. According to reports (Ptushenko, 1954; Stepanian, 1978, 1990, 2003), the bird nest to the east before Kokchetavskoy hill (about 70 o E). In Western Siberia is marked in the middle part Barabinskoy steppe (78 o E) MD Ruzskim (1946) and Yu.B. Pukinskim (1969). On the territory of Krasnoyarsk Region VI marked the first time Bezborodovym (1971): he met nest kamyshevok of Krasnoyarsk and the foothill of the reserve "poles" (93 o E), found two nests and vyvodki. SM Prokofiev (1987), did not specifically discuss this interesting fact leads Marsh Reed Warbler as usual nesting birds Minusinsk depression (Rogacheva, 1988) . We visually observed on several occasions, but catching and collection materials, this type does not exist, thus disagree with the recent approval (Savchenko, Baikal, 1996). Habitats. The main requirement of this kind of habitat - the availability of beds bushes - as close to water, and away from them, but always more or less humid, with thick Raznotravie. Prefer open (woodless) Camp - meadows, grassy marshes, fields zarosshimi mezhami, and if the wood, something very rare or fields or skirts. Very often, a few pairs nest in 10-30 meters of each other, so that there is razrezhennaya colony (Ryabitsev, 2001). Phenology. Priletayut later, in the south of the forest zone - only in late May - early June. Otletayut unseen, at night in late July - August (Ryabitsev, 2001). Reproduction. Nest typical of kamyshovok device podveshivayut, zapletaya his wall of vertical stems nettle, sorrel horse, swan or other hard grass or bushes low over the ground (rarely exceeding 1 m). Nesting over the water for this type is not true. Gnezdovoy material - dry stalks and leaves of cereals and other plants. In the tray, in addition to the thin blades are usually present scraping grains, small roots, often - horsehair. In laying 4-5, rarely 6 eggs. Their color white, light blue or greenish, spots of different intensity and size, greenish-gray, brown, olive. They are uneven and do not usually densely scattered on the surface of eggs, often concentrated at the blunt end. Eggs of this type are most similar to eggs drozdovidnoy kamyshovki - as if they reduced their copies. Dimensions eggs 16-22 x 13-16 mm. Nasizhivanie otkladki beginning with the penultimate egg. Sitting female and male alternately 12-14 days. A nest with eggs, poultry behave fairly discreetly and with the danger of trying to leave unnoticed, kept in the bushes and only pretend to vote. When vyluplyayutsya chicks, the parents when you flit around human rights with alarming shouts, dissolve the tail feathers vzeroshivayut and even click beak. The young vyluplyayutsya bare, with dark skin, mouth yellow, with two elliptical dark spots on the basis of language, klyuvnye rollers yellowish white. Sitting in the nest about 10 days and leave, not yet umeya fly steadily climb the stalk of grass and bushes (Ryabitsev, 2001). Nutrition. Pitaetsya gentle insects, which they collect, prygaya from stem to stem. In autumn, and even berries (Sauer, 1998). References. |
