Blue-winged teal, redhead, mallard, ruddy duck, coot, black tern, and yellow-headed blackbird next on the marsh. Fourmile Island State Natural Area supports the largest heron and egret nesting colony in Wisconsin. VIEW FROM BOAT ONLY. NO ENTRY ONTO FOURMILE ISLAND ALLOWED. The marsh’s more unique and secretive inhabitants such as the moorhen, sora, Virginia rail, pied-billed grebe, and American bittern are best viewed along the state canoe trail.
