SIRDS'-NESTS. 137

 almost all cases of joint interest, the female 

 bird is the most active. She determines the 

 site of the nest, and is usually the most ab- 

 sorbed in its construction. Generally, she is 

 more vigilant in caring for the young, and 

 manifests the most concern when danger 

 threatens. Hour after hour I have seen the 

 mother of a brood of blue grossbeaks pass 

 from the nearest meadow to the tree that 

 held her nest, with a cricket or grasshopper 

 in her bill, while her better-dressed half was 

 singing serenely on a distant tree or pursuing 

 his pleasure amid the branches. 



Yet among the majority of our song birds, 

 the male is most conspicuous both by his 

 color and manners and by his song, and is to

 thought that the female is humbler clad for 

 her better concealment during incubation.

 nature for her greater safety at all times, as
