Fishers Green which is part of the River Lee Country Park is especially important for birds in winter when ducks and other water birds visit from Northern Europe and Scandinavia. Other migrating birds such as waders, terns and warblers are best seen during spring and autumn.
In the summer, the Country Park is one of the best places in the country to see Kingfishers. With twelve bird hides and viewing screens, ten of which can accommodate wheelchairs, including the National Bittern Information point at Fishers Green, (Bitterns visit only between the end of October and the end of February), the River Lee Country Park is one of the best places in the country for birdwatching.
