BIRDS. 47 



180. Falco peregrinus Tunstall. Peregrine Falcon. 



Resident, now restricted to a pair or perhaps two breed- 

 ing annually among the Fells of the North-West, and 

 another on the cliffs of the coast, with an occasional pair in 

 Cleveland ; formerly it nested not uncommonly in suitable 

 localities. In autumn and winter immature birds are not 

 unfrequent on the coast, also occurring inland. 



181. Falco subbuteo Z. Hobby. 



Casual visitant, of uncommon occurrence in summer, but has 

 also been obtained several times in winter. As far as can 

 be ascertained it has nested in the county on three occa- 

 sions, at Rossington, near Doncaster (More, 1865), at 

 Bishop Wood, near Selby, in 1869 (W. E. C.), and at 

 Everingham Park, near Market Weighton (Boyes, 1875). 

 Fifty years ago this species is mentioned as being far from 

 uncommon in South Yorkshire. 



182. Falco aesalon Tunstall. Merlin. 



Resident, confined to the high western and north-eastern 

 moorlands, over which it is thinly scattered during the 

 breeding season. More generally distributed during the 

 autumn and winter. 



183. Falco vespertinus L. Red-legged Falcon. 



Accidental visitant from Southern and Eastern Europe, of 

 extremely rare occurrence.
