THE SWALLOW. 175 



Hirundinidcs drink upon the wing, and are 

 perhaps the only birds that do not alight for 

 this purpose, unless perhaps the Terns and 

 some of the Gulls may be also exceptions to the 

 general rule. 



With regard to their winter quarters and 

 geographical distribution, it will be best to trace 

 the movements of each species separately. 



The Chimney Swallow (ffirundo rusticd), 

 whose early appearance in the spring is only 

 preceded by that of the Sand Martin, spends at 

 least six months of the year with us, and in some 

 years more than seven months. The period of 

 its visit, however, may be said briefly to extend 

 from April to October. Between these two 

 months the bird is found generally distributed 

 throughout Europe, going as far north as Ice- 

 land 1 and Nova Zembla, 2 and penetrating even 

 into Siberia and Amurland. 3
