This bird is not found in any part of Thuringia. There are some in Silesia, Bohemia, Pomerania, near Wittenberg, Halle, and Dessau; but in Austria, Hungary, and Poland, they are in some districts more abundant than the common nightingale[85]. They generally settle among the bushes of the hills and plains, and especially near rivers. When caged they are fed like nightingales. They are less delicate, however, and live much longer. They are chiefly brought from Vienna to Thuringia, whence they have the name of Vienna Nightingales. Some people make a business of fetching them from Hungary, in the beginning of April, where they buy them cheap, in order to sell them very dear, in Saxony and other remote provinces. Those from Hungary are preferred to the Polish. A distinguishing characteristic is, that they first pronounce the _davitt_ or _jacob_ only once when they call; while the second repeat _davitt_ many times in succession. At Thorn, and all along the Vistula, where the common and the large nightingale equally abound, the latter is called the Polish Nightingale, and the former, the Nightingale of Saxony. The nest of the greater nightingale is built like that of the nightingale; but the eggs are larger, and of an olive brown, with dark shades. These birds are caught like nightingales; their diseases, also, are similar; but they appear to suffer still more when moulting; they become dull and ill, and often die under it. It is usual to give them at this crisis some spiders, and the grubs which gnaw wood; what, however, after many experiments, appears most salutary, is the Golden Tincture of Halle[86], one or two drops of which are poured into the drinking-trough.
