General Habits and Traits of Swallows 



Having already spoken at some length of tho two most 

 noticeable points in the economy of Swallows their migra- 

 tions and their architecture I may continue with some of the 

 other habits which birds of this family possess in common ; for 

 the group is so homogeneous that much of the material we have 

 acquired for separate biographies of the species furnishes the 

 occasion for remarks applicable to all.
