Southward, the Danube encircles a vast fen, tenanted only by waterfowl and herds of half-wild swine, while the plain which extends to the north-east and east only grows fertile at some distance inland.
The reeds are cover for waterfowl of various kinds, which the traveller sees in great numbers, and wild boars are found in the marshes to the south.
The fauna also is well represented, but tigers which once were frequently seen are now very scarce; panther, hyena, jackal, wild boar, deer (Cervus maral) are common; pheasant, woodcock, ducks, teal, geese and various waterfowl abound; the fisheries are very productive and are leased to a Russian firm.
Birds are very numerous, including no fewer than 4 varieties of crows, 5 of warblers, 7 of woodpeckers, 8 of buntings, 4 of falcons, and 5 of eagles; while among the hosts of waterfowl which people the marshes of the Danube are 9 varieties of ducks, and 4 of rails.
Waders and waterfowl are far less abundant, and those occurring are nearly all migratory forms which visit the peninsula of India - the only important exception being two kinds of solitary snipe and the red-billed curlew.
