BLYTH^S WREATHED HOUNBILL.

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. f rater - 
cuius 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. 
convexus 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 
are known.
