A warbler of wetlands, whose main characteristic is a striking light brown or whitish supercilium, a dark eye stripe, and a ‘warlike look’ resulting from the shape of its beak. The top of its head is dark and its back has mild stripes. They sing on willow branches and in reed, and they often go for a flickering song-flight for a short period of time in the middle of their singing. Sedge warblers are very lively and cautious birds, who hide in low bushes and herbage, where they move around in a skilled manner. They live in dense junipers, reed beds, and shrub swamps, as well as near overgrown trenches and lakes, flooded meadows, willow plots, etc. Sedge warblers usually make their nests near water. The nest is usually so well hidden that it is difficult to find it even when feeding the chicks. Sedge warblers are very beneficial birds. They eat insects, thereby contributing to keeping the natural balance in near-water bushes and reed-beds.
