NEST BUILDING 305 



as her window was planned in the same way but 

 was too small for use. Disappointed in this the 

 bird then greatly shortened the length of the hammock 

 in which her nest swung, so that she could brood 

 with her head free. There is no room for argument 

 about these nests; their structure proves v/hat I 

 record of them. 



A careful study of building and brooding Vjirds, 

 at least in the intimate relations required in making 

 photographic studies of them, will convince most 

 people that different birds of the same species have 

 different degrees of mentality and different charac- 

 teristics. Some are friendly and confiding, and 

 soon learn to trust one. Some are so nervous 

 and wild it takes patient work to win their con- 

 fidence, and some can not be won at all. Some 

 build in well-chosen places and make their work 

 secure, and some select their locations so unwisely 

 they see their nest destroyed before it is complete; 

 so it goes, very like humanity after all.
