The reed warbler occurs as a breeding bird from the boreal to the Mediterranean and steppe zone of the western and central Palearctic. Its height distribution extends from the lowlands to the lower mountain ranges. In north-western Europe the distribution is patchy, the southern limit of distribution is in the north of the Mediterranean and the Danube delta of Romania. There are partially fragmented occurrences in the southwest, the center and the east of Anatolia. The species is also found in the Crimea, Azerbaijan and northwestern Iran.
In almost all of Europe is long-distance migrant from April to October in attendance. He has his winter quarters south of the Sahara in Africa . Departure time and direction of movement are innate to him. In order to survive the 6,000 kilometers well, the night puller builds up fat reserves. The reed warbler lives in dense reeds and riverside bushes, in moors, swamps, on wet meadows and in cultivated land.
nutrition
The reed warbler feeds on insects , arachnids , smaller mollusks and berries .
Reproduction
Sexual maturity occurs after a year. The main breeding season is May to July. The nest is built low above the ground in thick vegetation. The female lays 4 to 6 eggs . The eggs are warmed alternately by both partners for 12 to 14 days. The young birds fledge after 10 to 12 days.
