are shot on the hills. The mole is in evidence everywhere up to the 1500 feet level, by the mole-heaps he leaves in every field, and the mole-catcher is a familiar character in most parishes. The squirrel has worked his way north during the last sixty years, and is now to be found in every fir-wood. The graceful roedeer is also a denizen of the pine-woods, whence he makes forays on the oat-fields. The red-deer is abundant on the higher and more remote hills, and deer-stalking is perhaps the most exciting as it certainly is the most exacting of all forms of Scottish sport. The pole-cat is rarely seen; he is best known to the present generation in the half-domesticated breed called the ferret. The hedge-hog, the common shrew, and the water-vole are all common. [Illustration: The Dunbuy Rock] The birds are numerous and full of interest. The coast is frequented by vast flocks of sea-gulls, guillemots, and cormorants, while the estuary of the Ythan has many visitants such as the ringed plover, the eider-duck, the shelduck, the oyster-catcher, redshank, and tern. On the north bank of this river the triangular area of sand-dunes between Newburgh and Collieston is a favourite nesting-place for eider-duck and terns. The nests of the eider-duck, with their five large olive-green eggs embedded in the soft down drawn from the mother’s breast, are found in great numbers amongst the grassy bents. The eggs of the tern, on the other hand, are laid in a mere hollow of the open sand, but so numerous are they that it is almost impossible for a pedestrian to avoid treading upon them. Puffins or sea-parrots are conspicuous amongst the many sea-birds that frequent Dunbuy Rock. This island rock, half-way up the eastern coast, is a typical sea-bird haunt, where gulls, puffins, razorbills and guillemots are to be seen in a state of restless activity. A colony of black-headed gulls has for a number of years bred and multiplied in a small loch near Kintore. A vast number of migratory birds strike the shores of Aberdeenshire every year in their westward flight. The waxwing, the hoopoe, and the ruff are occasional visitors, the great northern diver and the snow-bunting being more frequent.
