BLYTirS WREATHED HORNBILL. 91 



two thirds the length of the bill ; in old birds it is nearly as high as the 

 bill itself. 



Allied species from neighbouring regions are : A. affinis from Northern 

 India, similar in plumage to the present, but constantly larger; A.frater- 

 (H/HX from Cochin China, also similar in plumage, but said to have the 

 casque different in colour and shape. A. coronatus from S. India and A. 

 conrcxus from the Malay peninsula are also similar in coloration, but differ 

 notably in having the outer tail-feathers entirely white ; the former is larger 

 in size and the latter smaller. A. malayanus has the whole lower plumage 

 black and a broad supercilium white. 



The Small Pied Hornbill is found abundantly over the whole of British 

 Burmah. I know of no part of the province where it is not to be met with 

 all the year round. It occurs as often singly and in pairs as in small 

 flocks, and frequents every description of jungle, both dense forest and 

 outlying groups of trees. Fruit constitutes its chief food, but it also eats 

 reptiles and has been known to catch fish. I have frequently got the eggs 

 in March ; they are laid in a hole of a tree at a great height from the 

 ground, and are usually three in number, white, much stained with yellow 

 as incubation proceeds. The female is plastered up in her nest, as is 

 usual with all those species of Hornbills the breeding-habits of which 

 arc known.
