tanager may sometimes be found in summer by going around 

 the place from which the sound of its voice seems to come, or 

 by passing by it, and then returning to it. 



Many birds have the power of singing so softly that they 

 seem to be far away when really just at hand. The catbird 

 does this quite commonly, and many other species occasionally 

 sing their full songs in the fall as in the spring, except that they 

 are audible only a few yards away. In mild autumns, or on 

 warm days, some birds sometimes sing almost as well as in the 

 spring. To find birds one must cultivate the senses of sight 

 and hearing to the utmost.
