They can be easier to confuse with aquatic warblers due to an apparent pale central crown stripe contrasting with the darker edges. Volunteering is not only rewarding, but even just doing a little bit can have massive impact on local wildlife. Birds 69: 384-399.

This seems to be caused by an increasing early arrival on the breeding grounds in the first years. Migrants (especially in spring) can occasionally turn up in atypical habitat such as woodland or suburban gardens and may sing for a short while. In summer, the sedge warbler can be spotted singing from a reed or willow perch in wetlands across the UK. Ornis Scand.
