The Hebrides generally lack the biodiversity of mainland Britain, but like most of the larger islands, Skye still has a wide variety of species. Observing the abundance of game birds Martin wrote:
There is plenty of land and water fowl in this isle—as hawks, eagles of two kinds (the one grey and of a larger size, the other much less and black, but more destructive to young cattle), black cock, heath-hen, plovers, pigeons, wild geese, ptarmigan, and cranes. Of this latter sort I have seen sixty on the shore in a flock together. The sea fowls are malls of all kinds—coulterneb, guillemot, sea cormorant, &c. The natives observe that the latter, if perfectly black, makes no good broth, nor is its flesh worth eating; but that a cormorant, which hath any white feathers or down, makes good broth, and the flesh of it is good food; and the broth is usually drunk by nurses to increase their milk.
Similarly, Samuel Johnson noted that:
At the tables where a stranger is received, neither plenty nor delicacy is wanting. A tract of land so thinly inhabited, must have much wild-fowl; and I scarcely remember to have seen a dinner without them. The moor-game is every where to be had. That the sea abounds with fish, needs not be told, for it supplies a great part of Europe. The Isle of Sky has stags and roebucks, but no hares. They sell very numerous droves of oxen yearly to England, and therefore cannot be supposed to want beef at home. Sheep and goats are in great numbers, and they have the common domestic fowls."
In the modern era avian life includes the corncrake, red-throated diver, kittiwake, tystie, Atlantic puffin, goldeneye and golden eagle. The eggs of the last breeding pair of  white-tailed sea eagle in the UK were taken by an egg collector on Skye in 1916 but the species has recently been re-introduced. The chough last bred on the island in 1900. Mountain hare (apparently absent in the 18th century) and rabbit are now abundant and preyed upon by wild cat and pine marten. The rich fresh water streams contain brown...
