or moss, mixed with wool, fur of the rabbit, &c. ; the eggs from five 

 to six, of a light blue, a trifle darker at the large end, each weighing 

 about 43 grains ; the young hatched about the middle of May. 



It is believed, that this bird in general migrates annually, but I 

 am clear that some few remain through the whole year ; I have once 

 seen a single one a little after Christmas, and it is said, that some 

 have been occasionally observed about warrens, and stone quarries, 

 during the winter : the greatest number seen on the downs in Kent, 

 as far as my own observations go, is about the middle of April,* and 

 after staying a fortnight, rarely more than one or two remain, but 

 return to the same spot in August, as we are told, though I cannot 

 say that I have remarked this return, oftener than twice or thrice. 

 Mr. Boys once informed me, that he had frequently seen them in 

 plenty about Sandwich, the second week in August. 



This species inhabits the whole of the Continent of Europe, from 

 Greenlandf on the north, to the Cape of Good Hope, and from thence 

 at least to the East Indies, as we have not only met with drawings 

 of the bird, but seen specimens, which were brought from that part 

 of the world; J but it is in all places described as migratory; are 

 frequently known to fly on board of ships on entering the Straits of 

 Gibraltar, coming from the Barbary Shore, and observed to arrive in 

 that fortress from the end of March to the second week in April in 

 numbers; a few stay, and breed there, but the rest depart northward ; 

 returning again to the rock in September, after which they dis- 

 appear for the winter.
