THE BIRD-LIFE OF A YEAR 23 



traits which at other times of the year they give no 

 evidence of possessing. Singing now reaches its 

 highest development, and certain call-notes are 

 heard only at this season. The numberless actions 

 incident to courtship ; the intelligence displayed in 

 nest- building; the choice of special food for the 

 young ; the devotion which prompts the parents 

 to recklessly expose themselves in the protection 

 of their offspring all these manifestations of the 

 bird-mind may be observed in June. 



A feature of the bird-life of the month is the for- 

 mation, usually in young second-growth woods, of 

 roosts which are nightly frequented by the now 

 fully grown young of such early-breeding birds as 

 the Purple Grackle and Robin. When a second 

 brood is raised, as with the Eobin, the young of the 

 first brood may be accompanied to the roost by 

 the male parent, but in the one-brooded Grackle 

 the roost is used by both adults and young.
