'The rock (or ring-ouzel) hath always hitherto 

 t>een confidered as frequenting only the more moun- 

 tainous parts of this iiland : Mr. White, however, 

 •informs me that there is a regular migration of thefe 

 birds, which flock in numbers, and regularly vifit the

 flocks of thefe birds appear constantly every year in

 fond of the feeds of thefe trees, and therefore 

 changes its place to thofe parts where it can procure 

 the greater! plenty of iuch food f .

 North.
