Frequents river banks and overhanging tree-roots. Flits its 

 wings like a Kinglet (Regulus), flashing its bright rump. Has a beau- 

 tiful clear ringing song, somewhat like that of the Ovenbird (Seiurus 

 awocajnllus), but more striking because the crescendo rises higher. 

 The bird also walks like an Ovenbird and feeds along the water's edge 

 like a Water Thrush (S. vovehoracensis).
