 that that end is at length attained. 

 Hence, in a general way, the instinct of song

 territory, 



Now the subsequent course of behaviour 

 tends to confirm this view. We have already 

 had occasion to refer to the fact that the males 

 of some species desert their territories temporarily 

 and join together on ground which is regarded 

 by the birds that associate there as neutral, and 

 that they do so not merely for the purpose of 

 securing food but because they derive some 

 special pleasure from the act of association, and 

 we shall find that the altered behaviour of the 

 male when it leaves its territory to seek food or 

 to join the flock is an important point for us 

 just now. 



Buntings desert their territories temporarily 

 and collect in flocks on the newly sown fields of 

 grain. Some of the males are single, others are
