4 THE SCOTTISH NATURALIST 



Buzzard, Buteo buteo. 



The Common Buzzard is not a native of the Corrour Forest, but 

 is not uncommon in a neighbouring domain where there are sparsely 

 wooded cliffs on which it nests. From this haunt the bird 

 occasionally visits the neighbourhood of Lochs Ossian and Treig. 



Golden Eagle, Aquila cluysactus. 



Three pairs of this fine characteristic Highland bird are natives 

 of the Forest. I visited their eyries in June last for the purpose of 

 ascertaining their altitudes, and the nature of the chosen sites. All 

 were placed on crags with a more or less steep face of rock below 

 and above them, and they were also all recessed, and would thus 

 escape the rush of the wind from all quarters. Their front aspects 

 were easterly. In one instance there were alternate sites not more 

 than 10 feet apart. Their altitudes were respectively 1950, 2050, 

 and 2420 feet. 



Peregrine Falcon, Falco peregrinus. 



Two or three pairs are natives of the Forest, where they nest 

 on the precipitous faces of crags at altitudes ranging from 1750 to 

 1850 feet. This bird is present during the winter, but probably 

 not in the same numbers as in the spring. I saw one, or more, in 

 December, stooping down upon the open spaces in the birch wood 

 for the purpose of putting to flight both Black and Red Grouse 

 which were feeding there.

Merlin, Falco (r,salo?i. 



This species appears to be quite a rare bird in the Forest, for it 

 has only come under my notice in summer on the wild moorland 

 ground, at 1150 feet, bordering the Blackwater Loch. 



Kestrel, Falco tinnunculus. 



Is quite common in summer, and nests on the rocky faces 

 in various parts of the Forest at elevations as high as 2000 feet. It 

 is not, however, found in the woods. Its presence at Corrour in 

 the winter is doubtful. 



Sparrow-Hawk, Accipiter nisus. 



A pair nests annually in the birch wood, to which the bird 

 is a summer visitor. The site of the nest varies, but is usually from
