Twenty creatures, furred and feathered, have undergone severe persecution since the extension of pheasant-covers, and of these the first nine have more or less succumbed--namely, pine-marten, polecat, eagle, buzzard, falcon, kite, horned owl, harrier, and raven. The remaining eleven have survived--namely, stoat, weasel, rat, crow, kestrel, sparrowhawk, brown and barn owl, jay, magpie, and woodpecker. Pheasants of themselves are not responsible for all this warfare and all these changes; but the pheasant-cover means more than pheasants, or rather has done. Rabbits required even more protection from furred enemies; the head of rabbits kept up in many places practically paid the keeper's wages. This warfare in its fiercest form may be roughly said to be coeval with the invention of the percussion gun, and to have raged now for over half a century. The resistance, therefore, of the various species has been fairly tested, and we may reasonably conclude that no further disappearance will take place, unless by the destruction of woods themselves. One new bird only has been introduced into England since the pheasant--the red-legged partridge which seems to be fairly established in some districts, not to the entire satisfaction of sportsmen. One new bird has also been introduced into Scotland--in this case a re-introduction. The magnificent capercailzie is now flourishing again in the north, to the honour of those who laboured for its restoration. In these notes I have not included attempts at acclimatisation, as that of the wild turkey from North America, which has partly succeeded. Beavers, too, have been induced to resume possession of their ancient streams under careful supervision, but they are outside present consideration. While England has thus lost some species and suffered a diminution of several, other countries have been supplied from our streams and woods and hedgerows. England has sent the sparrow to the United States and Australia; also the nightingale, rabbit, salmon, trout, and sweet-briar. It is quite open to argument that pheasant-covers have saved as well as destroyed. Wood-pigeons could scarcely exist in such numbers without the quiet of preserved woods to breed in; nor could squirrels. Nor can the rarity of such birds as the little bearded tit be charged on game. The great bustard, the crane, and bittern have been driven away by cultivation. The crane, possibly, has deserted us wilfully; since civilisation in other countries has not destroyed it. And then the fashion of making natural history collections has much extended of recent years: so much so, that many blame too ardent collectors for the increasing rarity of birds like the crossbill, waxwing, hoopoe, golden oriole, and others which seem to have once visited this country more commonly than at present.
