Great egrets (Ardea alba) have been recorded in Kvismaren for several years. In the summer of 2025, they are breeding in Kvismaren for the first time! The bird observatory's staff have located a colony with five nests. When the chicks are large enough, they will be ringed.

We had two field workers throughout the spring. Wetland surveys recorded high numbers of Black-headed Gulls, Little Gulls, and Marsh Harriers. Great Reed Warblers and Savi’s Warblers were unusually abundant, particularly at Fågelsjön, Kvinnerstasjön, and Sörbysjön.

In 2025, Kvismare Bird Observatory ringed 4,350 birds and recorded several rare species. Major habitat restoration to benefit birds and visitors continued around the area.

The first members of this year’s field team have now arrived at the bird observatory, and the field season is officially underway. Initial work has included monitoring Starling breeding activity in nest boxes located throughout the area, as well as surveys of passerines in the reedbeds and wetland birds in different parts of the reserve.

During a busy summer season, Kvismare Bird Observatory carried out extensive monitoring, wetland surveys, and ringing activities, recording about 4,300 ringed birds by mid-August. Several wetland species bred successfully, and long-term studies of farmland and reedbed birds continued despite limited staffing and water-level challenges.
