Lined by marshes and flooded woodland, the Danube supports a wide array of species including Night Heron, Great White Egret and in winter geese and White-tailed Eagle. Smaller species in summer include River and Savi's Warbler and Penduline Tit whilst at the other extreme, west of Kamarno is a reserve supporting significant numbers of Great Bustard.
