Description

Slightly smaller and more graceful than other warblers, devoid of streaks, a little more compact structure. The wing is short, rounded, folded wings slightly protrude backward, like in the garden warbler. Body length 12–14 cm, wingspan 15–18 cm, weight 10–17 g. The manner of moving over reeds and other herbaceous near-water plants is similar to other warblers.
Another kind of evenly colored warblers, devoid of streaks, brownish-beige above and light below. In general, it differs in a slightly more contrasting color of plumage than in other "non-pedigree" warblers. The light eyebrow is more pronounced than in the garden warbler, and noticeably better than in the reed and marsh warblers, and unlike these species, it is bounded from above by the darkish edges of the “cap”, and from below by a relatively dark cheek, which makes it more contrasting. The light ring around the eye is almost imperceptible. The top is unevenly colored: the crown is darker than the back, the upper tail with a noticeable reddish-brown bloom, this feature distinguishes this species not only from closely related species of warblers, but also from warblers and warblers. Underparts are light, almost white, including the throat and sides of the chest.it contrasts well with the brownish-olive coloration of the upper body; beige bloom is present only on the plumage of the abdomen and on the undertail. On tertiary flight feathers there are no contrasting light edges, like in the marsh warbler. The bill is slightly shorter than that of other warblers, usually two-colored - the base of the mandible is yellowish, the rest of the bill is dark, almost black. Eyes brown in different shades. The legs are dark brown. The oral cavity is yellow.
The song is a set of various signals typical for warblers, includes few crackling syllables, also with a large number of borrowings. It does not have a clearly defined initial solo, like the garden warbler, few high “meowing” sounds characteristic of the reed warbler; the song is performed relatively slowly, “legibly”, with pauses between syllables, i.e. without "running over" of one syllable to another, as in the marsh warbler. Calling is a characteristic of all warblers "chche, chche".

Spread

An Asian species, the nesting area covers the southern and central regions of Eurasia from the Black Sea region to the Far East; in recent decades, there has been a gradual expansion of the range in the northern direction up to the Middle Volga region, Kirov and Perm regions. Wintering grounds are located in the south of Asia. In European Russia, the northern border of the nesting area can be drawn rather tentatively, since isolated nesting sites north of the main area are known, and in a number of areas the species may have been missed. In its characteristic habitats, it is numerous, in the northern part of the range it is scarce or rare.Arrives in late April or May; departure occurs in August and September.

Biology

Like the reed warbler, it inhabits various varieties of reed thickets, more often in places where they grow in relatively dry areas or where the remains of last year's dry reeds accumulate. Flooded, fresh reed thickets, if not avoided, then does not prefer them, like the reed warbler. In places with such vegetation (fish ponds, etc.) it penetrates far to the north of the main nesting area. The nest is of a design typical for most warblers; it is a thick-walled, relatively massive structure made of plant materials, mainly of reed panicles; its walls are entwined with supports. Often located very low, in the densest creases of last year's reeds, usually well camouflaged. Clutch contains 3–6 dirty greenish or brownish eggs with small brownish specks. The female incubates the clutch for about 13 days; the males are prone to polygyny, i.e. to pairing with two females. Both parents are involved in feeding the chicks. They feed on insects, which are collected from the surface of plants or from the water's edge, there is no tendency to catch insects in the air.
