VERTEBRATES: BIRDS, FISHES. 575 



seen by the writer in the Castle grounds near Stornoway. 

 A species of Wren is found in St. Kilda which is peculiar 

 to that island. The Starling, Rock Pigeon, Common 

 Thrush, the Fieldfare, and the Redwing are also to be 

 seen in great numbers. 



Of the predatory species there are the White-tailed Sea- 

 eagle, Golden Eagle, Sparrow-hawk, Hen-harrier, Kestrel 

 Raven, and the Hooded Crow. 



The common sea-birds include the great Glaucous Gull, 

 the Black-backed Gull, the Herring Gull, and the Common 

 Sea-Gull, the Cormorant, the Crested Cormorant, Great 

 Northern Diver, the Puffin, Fulmar and others of the 

 Petrel family. 



Along the shores are to be found the Golden Plover 

 Sanderling, Oyster-catcher, Ring Plover, Turnstone, Lap- 

 wing, Common Heron, Curlew, Dunlin, Purple Sandpiper, 

 Red Shank, Rock Pipit, Common Pipit. 



It has been observed that the number of land birds in 

 winter is much larger in the South of Scotland than it is 

 in the North, whereas shore and sea birds are more numer- 

 ous in the North than they are in the South of Scotland. 



For an exhaustive account of the birds of the Outer 

 Hebrides the works of Macgillivray and Harvie Brown are 

 recommended to such as are desirous of following up this 

 most fascinating part of the fauna of the Outer Hebrides. 



THE FISHES OF THE OUTER HEBRIDES. 



As the geographical situation of the Outer Hebrides lies 

 within the North Atlantic province, the Arctic fauna which 

 has invaded it diminishes in the number of individuals of 

 each class the farther the northern invaders have gone 

 within its area. What the fauna has gained in variety of 

 classes it has lost in the numbers belonging to each class. 

 The same remark holds good for the representatives of the 

 Mediterranean fauna which also are found within this por- 

 tion of the North Atlantic province, which Forbes rightly 

 named the Celtic Province or, rather, Sub-Province.
