There is no doubt that many other species of these birds must or may appear during the flights, but only naturalists who are accustomed to live in that neighbourhood can make a complete list. That, however, in our case is not very important, because it is rather difficult to find a very rare water or shore bird in those districts, though we may easily meet other species, as Dunlins, Sandpipers, Water-Rails, Crakes, Coots, Gulls, Terns, Grebes, &c., which are not uncommon in the neighbouring open plain, where they can live at their ease. As these places are not adapted for them, they may appear here only as stragglers, or in the flight-time as irregular ones; but this fact seems to me of very little interest, for I firmly believe it exceedingly difficult to find Sociable Lapwings, Phalaropes, Purple Sandpipers, Bartram's Sandpipers, Bernicle Geese, Scoters, and Skuas here, or the many other birds of rare appearance in our subregion, which offer a particular interest to the Italian ornithologists.
