MIGRATION OF BRITISH BIRDS. 515 



the Dottrel appears in Tpring and in 

 autumn, yet what is very lingular we 

 do not find it breeds here. The 

 Sea Pie lives with us the whole year. 

 The Norfolk Plover and Sea Lark 

 breed in England. 



We muit here remark, that every 

 fpecies of the genera of Curlews, 

 Woodcocks, Sandpipers and Plovers $ , 

 that forfake us in the fpring, retire to 

 Sueden, Poland, Pruffia, Norway, 

 and Lapland to breed ; as foon as the 

 young can fly, they return to us 

 again ; becaufe the frofts which let 

 in early in thofe countries totally de- 

 prive them of the means of fubfift- 

 ing ; as the drynefs and hardnefs of 

 the ground in general during our 

 fummer prevent them from pene- 

 trating the earth with their bills, in 

 fearch of worms, which are the na- 

 tural food of thefe birds. 



* Mr. Ekmarck fpeaks thus of the retreat of the whole tribe of 

 cloven footed water fowl out of his country (Sueden) at the ap- 

 proach of winter ; and Mr. Klein gives much the fame account of 

 thofe of Poland and TruJJia. 



Gralla (tanquam conjuratas) unanimiter in fugam fe conjiciunt, 

 ne earum unicam quidern inter nos habitantem invenire poffumus. 

 Aman. Acad. iv. 588. 



Scolopaces et Glareoles incredibilibus multitudinibus verno tempore 

 in PoloniatiBaruJJla nidulantur; appropinquante autumno turmatim 

 fvolant. Klein de ay. err at. 187.
