Fowlmere is a Royal Society for the Protection of Birds nature reserve between Fowlmere and Melbourn in Cambridgeshire. It is designated a 39.9 hectare biological Site of Special Scientific Interest called Fowlmere Watercress Beds. Fowlmere's reedbeds and pools are fed by natural chalk springs and a chalk stream runs through the reserve. It has three hides, one of which is wheelchair-accessible. Special birds include kingfishers, water rails, sedge warblers, reed warblers and grasshopper warblers plus a roost of corn buntings in winter.
