This species resembles Zarhynchus w. wagleri 

 in habits and in many of its notes, though it was 

 not heard to make the crashing sound and deep 

 liquid notes. It was found nesting in the 

 same tree with that species up the Chilibri River 

 in January, 1923 and 1924. In such cases its 

 nests, which are shorter and smaller, are usually 

 grouped near together.
