"Thrushes are not like other birds of passage which lay their eggs in particular places, as the swan does in the fields and the swallows under the roof, but they lay anywhere: for, despite their masculine name (_turdus_) there are female thrushes, just as there are male blackbirds, although they have a purely feminine name (_merula_). "All birds are divided as between those which are of passage, like swallows and cranes, and those which are domestic, like chickens and pigeons: thrushes are birds of passage and every year fly from across the sea into Italy about the time of the autumn equinox, returning about the spring equinox. At another season doves and quail do the same in immense numbers, as may be seen in the neighbouring islands of Pontia, Palmaria and Pandataria, for there they are wont to rest a few days on their arrival and again before they set out across the sea from Italy." _b. For pleasure_ "So," said Appius to Axius, "if you enclose five thousand thrushes in such an aviary as Merula has described and there happens to be a banquet or a triumph, you will gain forthwith that sixty thousand sesterces which you so keenly covet and be able to lend the money out at good interest." And then, turning to me, he added, "Do you tell us of that other kind of ornithon, namely: for pleasure merely, for it is said that you have constructed one near Casinum which surpasses not only the original built by the inventor of such flying cages, our friend M. Laenius Strabo of Brundisium (who was the first to keep birds confined in the chamber of a peristyle and to feed them through the net), but also the vast structures of Lucullus at Tusculum."
