34 Manual of the Game Birds of India. 



head is not always clearly defined ; from 

 the eye to the tip of the nail about 47 ; 

 from the gape to the tip of the nail 

 about 3*8. The wing measures about 

 23. The tail is between 9 and 10 in 

 length, and much pointed, the distance 

 between the tip of the outermost feather 

 and the tip of the middle pair of feathers 

 being nearly 4. The tarsus is about 3*8 

 and the middle toe, with claw, about 6. 



The adult male has a knob at the base 

 of the upper mandible. The adult female 

 has a similar, but smaller, one. Young 

 birds have no indication of a knob. 



Adult birds have the bill orange-red, 

 except the knob, the skin between the 

 eye and the bill, an elongated patch on 

 the nostril, the nail and margins of both 

 mandibles, and the base of the lower 

 mandible, which are black ; the irides are 

 brown ; legs and feet black. 



In young birds, the orange colour of 

 the bill is replaced by fleshy grey or pale 

 buff, which frequently turns to a blackish 

 colour in dry skins. 



The total length of an adult bird is 

 about five feet. The weight of Indian- 

 killed birds has varied from 13 to 19 Ib. ; 

 but tame birds in Europe are said to 

 reach a weight of 30 Ib.
