Pheasants and partridges cannot be said to be Alpine birds; but the Greek partridge may be so considered.
Numbers of the mountain streams and tarns contain excellent trout, and most of the larger lakes are well stocked with fish. Some of the trout of the Swiss and Italian lakes are of great size. The pike frequently weigh twelve to fifteen pounds.
Reptiles are not numerous. The common frog, which is said to be found as high as ten thousand feet above the sea, swarms in some parts of the Rhone Valley. Of true lizards, five species have been recognized. The blind-worm (which is not a snake), so common on many of our English heaths, is often met with. Among the true snakes we find the English ringed snake—quite harmless—and two adders. The common adder is found at a height of seven thousand feet above the sea.
Lower forms of life not possessing a backbone (invertebrates) abound in this region; but they are far too numerous to be considered here. Butterflies and moths are abundant; and many of those which are rare in England are common in the Alps, so that the entomologist finds a happy hunting-ground. The beautiful swallowtail and the handsome apollo, coppers, painted ladies, fritillaries, and many other Lepidoptera thrive in these regions, and are less easily frightened than at home in England.
