Younc) birds are much browner than the adults, but show very 

 little trace of the pale margins which characterize the immature 

 birds of the various species of Halcyon. They have a broad collar 

 of dark brown across the fore neck, and show very little green on 

 the wings or tail. As the adult plumage is assumed the green 

 becomes more prevalent, and the brown band on the neck dis- 

 appears.
