Savi’s warbler
Savi’s warbler is a common but relatively local reed warbler in Lääne County. The species’ primary breeding grounds are Matsalu National Park (about 3000 pairs) and Silma Nature Reserve (300–500 pairs), where it thrives in mosaic reed habitats that grow in water. The chirping of Savi’s warbler is extremely loud at dusk. The best time to hear their song is between late April and mid-June. The greatest spots to listen to birds in Matsalu are Port Kiideva, the mouth of the Kasari River and the Sutlepa Sea observation towers near Noarootsi.
