62 BIRDS. 



Beverley, one about 1869, seen in the flesh by Mr. W. W. 

 Boulton (Cordeaux, Birds of Humber, p. 81). 



254. Perdix cinerea Lath. Partridge. 



Resident, generally distributed, abundant. Mentioned as 

 scarce at Halifax and in Upper Ribblesdale. 



255. Coturnix communis Bonnat. Common Quail. 



Summer visitant, breeding regularly in limited numbers, in 

 Holderness and at Boston Spa, and irregularly in many 

 other localities in the county. Has occurred occasionally 

 in midwinter. Many records show that this species was 

 formerly much more frequent, and Mr. A. Strickland in- 

 formed Mr. Allis (1844) that they used to be taken in nets 

 near Bridlington. 



256. Ortyx virginianus (L.). Virginian Colin. 



Accidental visitant from Eastern North America, of extremely 



rare occurrence. 







Cottingham, male, 'a few years since,' in the collection of Mr. 

 Boulton (Cordeaux, Birds of Humber, 1872, p. 83). 



Fam. TETRAONIDJE. 



257. Lagopus mutus Leach. Common Ptarmigan. 



258. Lagopus scoticus (Lath.). Red Grouse. 



Resident, abundant on all the high moors, and in severe 

 winters sometimes occurs as a straggler in the most unlikely 

 localities. The Rev. H. H. Slater informs me on the 

 authority of his uncle, Mr. T. Horrocks, of Eden Brows, 

 Carlisle that towards the end of October every year there 

 is a migration of packs of grouse from the Duke of Cleve- 

 land's moors, near High Force, in Upper Teesdale, to Mr. 

 Horrocks' moors, at Alston, in Cumberland (a distance of 

 twenty miles), where they remain until the end of the season, 

 and then return to their own county. A large proportion 

 of these migrants are hens, and they are different in size 

 and plumage and readily discriminated from the Alston 

 birds, being only two-thirds their size and weight, and their 

 plumage more speckled and yellow.
