/ *1T A HIS fpecies is the largeft of our fwallows; 



-*■ but the weight is mod difproportionately fmall 

 to its extent of wing of any bird ; the former being 

 ■fcarce one ounce, the latter eighteen inches. The 

 length near eight. The feet of this bird are fo fmall 

 that the action of walking and of riling from the 

 ground is extremely difficult; fo that nature hath 

 made it full amends by furnifhing it with ample 

 means for an eafy and continual flight. It is more 

 on the wing than any other fwallows; its flight is 

 more rapid, and that attended with a fhrill fcream. 

 It refts by clinging againft fome wall, or other apt 

 body; from whence Klein ftyles this fpecies Hirundo 

 muraria-. It breeds under the eaves of houfes, in 

 lleeples, and other lofty buildings. It is entirely of Defer. 

 a footy color, only the chin is marked with a white 

 fpot, The feet are of a particular ftructure, all the 

 toes {landing forward ; the left confifts of only one 

 bone ; the others of an equal number, viz. two each ; 

 in which they differ from thofe of all other birds. 



This appears in our country about fourteen days 

 later than the fand martin ; but differs greatly in the 

 time of its departure, retiring invariably about the 

 middle .*&£&/?, being the firft of the genus that leaves us.
