The wonderfully high, arched bill alone would, for us, not be sufficient to 

 separate this bird generically, but the curious development of the coloration from a 

 more or less whitish young through an intermediate bluish grey state to the adult 

 raven-black plumage, is some reason for separation from Corciis in which both yonug 

 and old are lilackish. 



<Ti/mnocorvus shows a somewhat similar case.
