The rock (or ring-ouzel) hath always hitherto been confidered 

 as frequenting only the more mountainous parts of this ifland : 

 Mr. White, however, informs me that there is a regular migra- 

 tion of thefe birds, which flock in numbers, and regularly vifit 

 the neighbourhood of Selborn, in Hamplhire 2 .. 



I therefore have little doubt but that they equally appear in 

 others of our Southern counties though it efcapes common 

 obfervation,. as they bear a fort of general refemblance to the 

 black-bird r at leaft to the hen of that fpecies- 



I own alfo, that I always conceived the Bohemian chatterer 

 was not obferved in Great Britain but at very diftant intervals of 

 years, and then perhaps only a Angle bird,, whereas Dr. Ramfey 

 (profeffor of natural hiftory at Edinburgh) informs Mr. Pennant, 

 fehat flocks of thefe birds appear conftantly every year in the neigh- 

 bourhood of that city \ 



As for crofs-bills, they are feen more and more in different 

 parts of England,, lince there have been fo many plantations 

 of firs :. this bird is remarkably fond of the feeds of thefe trees, 

 and therefore changes its place to thofe parts where it can pro- 

 cure the greateft plenty of fuch food b .

a Thefe birds are faid to be particularly fond of the berries of thV 

 mountain-afh, which is an uncommon tree in the Southern parts of Great 

 Britain, but by no means fo in the North. 



b This bird Ihould alfo, for the fame reafon, be found from year to 

 year in the cyder counties, if it was true (as is commonly fuppofed) that 

 he. is particularly fond of the kernels of apples, which it is conceived he 

 can inftantly extract with his very lingular bill. 



Mr. Tun flail, F. R. S. however, at my defire, once placed an apple 

 in the cage of a crofs-bill, which he had kept for fome time in his very 

 valuable and capital collection of live birds. Upon examining the apple 

 a fortnight afterwards, it remained untouched. The notion of this bird, 

 however, feeding on apple-kernels, is very antient. A. D. 1251, quzedam
