MNIOTILTID^ — THE AMERICAN WARBLERS. 161 



times placed within a few yards of one another. It is usually seen 

 upon the wet ground or wading in the shallow water, its body in 

 a horizontal position or even more elevated posteriorly, but contin- 

 ually tilting up and down, and when moving about it progresses by 

 a graceful gliding walk. If it fancies itself observed, it runs slyly 

 beneath the brush- or drift-wood overhanging the shore ; and if 

 alarmed, flies up suddenly with a sharp and startling chatter. 



Audubon describes the song of this species as fully equal to that 

 of the nightingale, its notes as powerful and mellow, and at times 

 as varied. This may be true of the ecstatic love-song, heard on 

 rare occasions, and uttered as the singer floats in perfect abandon 

 of joy, with spread tail and fluttering wings; but it can hardly be 

 true of the ordinary song, which, although rich, sweet, and pene- 

 trating, and almost startling in the first impressions it creates, is 

 soon finished, and the pleasing effect somewhat transient. 



It cannot be denied, however, that its song is one of the richest 

 to be heard in our forests.
