HENICORNIS PHCENICURUS. 173 



are very playful, frequently pursuing and wheeling about each other, 

 and uttering a sharp, trilling note. On a warm day in winter they are 

 occasionally heard attempting to sing, the bird darting up vertically 

 into the air and pouring out with great energy a confused torrent of 

 unmelodious sounds. 



Their habits, so much less sedate and strikingly in contrast with 

 those of most of the birds in this family, are no doubt due to the 

 greater powers of flight possessed by Cinclodes.
