The Peregrine Falcon.'\ OF ORKNEY. 151 



lume of the British Zoology. It is hkewise found in Mar- 

 wicii-head, Hoy, Walls, Copinsha, and elsewhere in Orkney; 

 likewise in the Fair Isle and Foula ; as also in Lamhoga of Fet- 

 lor, Fitful, and Sumburgh-Heads of Shetland. 



Never more than one pair of this species inhabit the same 

 rock ; and when the young are fit, they are driven out to seek 

 new habitations for themselves. The falcon's nest, like the 

 eagle's, is always in the very same spot, and continues so past 

 memory of man.
