" The sexes of this Hornbill may be distinguished by the posterior 
surface of the horn above the forehead, being black in the male, and 
concolorous with the rest of the horn in the female ; besides which, 
the male has a black line dividing the bill and casque, and continued 
forward and upward upon the latter, parallel with its anterior 
margin."— (Blyth.) 
Captain P. J. Begbie says : " What the precise use of the hollow 
protuberance surmounting the bill is, I am unable to say, but I 
think it not improbable that a communication exists between it and 
the larynx, producing the shrill and grating cry uttered by the bird, 
which is heard when it is soaring even at a great height. The 
Hornbills build on the tops of the loftiest trees, and are extremely 
shy, seldom permitting the sportsman to approach within range. 
When taken alive, they make a strenuous resistance with their long 
and powerful wings."
