 song of this bird is a rapid, intricate warble, like 

 that of the indigo- bird, though stronger and louder. 

 Indeed, these two birds so much resemble each

 and how skillfully is the nest concealed ! We occa-

 sides, and finally left it with much reluctance. 

 The nest, which contained three young birds nearly
