This interesting little bird is distributed all over the North Island, but is replaced in the South 

 by a representative species, the Ortlionyx ochrocephala or Yellow-head. 



It frequents all vs^ooded localities, but seems to prefer the outskirts of the forest and the low 

 bush fringing the banks of rivers and streams. It is gregarious in its nature ; and the report of 

 a gun, the cry of a Hawk, or any other exciting cause will instantly bring a flock of them
