General information. Of all the warblers in Finland, the sedge warbler is the most abundant and widely distributed. It nests throughout the country, as far as the northern tip of Lapland. The nesting population, however, is largest in the southern parts of Finland. Nesting populations have remained stable over the past few decades.

  • Length 13 cm
  • Nests in reed beds, under bushes and in tussocks under vegetation cover
  • Winters in Africa
  • Feeds on insects

Habitat. The sedge warbler is more flexible than other species when concerning its habitat. Most commonly, the sedge warbler is found in waterfront reed beds, where it is usually the most plentiful nesting species in the area. In addition to reed beds, it can also be found nesting in dense, roadside willow thickets, overgrown marginal lands and bulrush vegetation in lowland moors.

Distribution in Vaasa. The sedge warbler occurs in suitable habitats all over Vaasa. During the field work, the species was observed in a total of about 100 survey blocks. It occurs primarily in reed beds along the city waterfronts, for example by the Sundominlahti bay. It can also be found nesting in the archipelago.
