p. 73S). There can be little doubt that Macgillivray's in- 

 formant made a mistake, and that the species in question was 

 the Peregrine. 



Falco peregrinus. 



The Peregrine breeds sparingly on the cliffs, two or three 

 pairs only tenanting the most inaccessible portions of the 

 islands. The lofty pinnacles of Doon are the bird's favourite 

 haunt. 



Falco tinnunculus. 



The Kestrel occasionally visits St. Kilda, but I could find 

 no evidence of its ever breeding there. 



Aluco flammeus (?). 



Donald M'^Queen told me that he remembered an Owl 

 caught here many years ago, which, from his description, I 

 took to be the Barn-Owl. 



TURDUS MUSICUS. 



I include the Song-Thrush as a bird of St. Kilda on the 

 authority of Sir William Milner. It probably occurs on 

 migration. 



TuRDus TLiAcus. '' Smcorach." 



The Redwing is seen on St. Kilda during its annual 

 migration, in May and September, in flocks. 



Merula merula. '' Lon-dutha." 



The Blackbird" visits St. Kilda on spring and autumn 

 migration, but never remains to breed. 



Saxicola (ENANTHE. " Clacharau." 



The Wheatear is very common on St. Kilda, and is one of 

 the most conspicuous land-birds as it flies to and fro over 

 the stony hillsides. I did not observe it on Doon. 



Troglodytes hirtensis, Seebohm. (Plate III.) 

 The most interesting result of my trip to St. Kilda was the 

 determination of its Wren, called " Dhra-in-doun '' by the 

 natives. Although this little Wren was known to Martin 

 nearly two hundred years ago, neither he nor any subse- 

 quent naturalist had the least idea that the bird was difi'erent
