SOME MINOR SONG-BIRDS. 161 



blue-bird in its nest-habit offers for our study 

 one of those curious contradictions now and 

 then appearing in nature. Instead of building 

 a graceful nest, swung airily amid the fragrant 

 foliage, it dives into some gloomy, unsightly 

 hole in a rotten stump or tree, and there, like 

 the kingfisher in his subterraneous cavern, 

 rears its brood. Querulous, saucy, bold, this 

 beautiful little creature has endeared itself to

Our indigo-bird, bluer than the last-named

 but a little distance. When it is caught in its 

 completeness, however, the melody is so child-

 wood-thrush. Its shy habits, and the chary 

 parsimony with which it doles out its vocal 

 favors, have, no doubt, tended to prevent its 

 becoming popular, even with good observers. 

 There is a silvery ring in its higher notes and
