A common and characteristic bird of the 

 Zone. Frequents clearings and low bushes, in- 

 cluding the vicinity of habitations; often seen 

 on the ground. Its call, which is frequently 

 heard in the spring months, consists of a repeti- 

 tion of the same short note, beginning slowly 

 and increasing in rapidity until it very nearly 

 merges into a continuous sound. It is one of the 

 most characteristic bird calls of the Canal Zone.
