30 CORVID2. 
Description. This race is distinguished from the Himalayan 
bird by its long, very stout bill and from the other races by its 
greater size. 
Measurements. Wing about 325 mm.; the males run from 
304 to 345 mm. and the females from about 290 to 321 mm, 
The bill is very long, never under 58, generally well over 60 and 
running up to 70 mm., the average being about 65 mm. In 
addition to its length it is stouter and heavier than in any other 
form. 
Distribution. Andamans, Assam, Burma, and North and 
West Siam. I cannot find any satisfactory character which 
suffices to separate the Andaman birds from the others. In all 
the island adults the bases to the feathers are very pure white, 
whereas in the Assam and Burmese birds they range from almost 
pure black to more than equally pure white. Northern birds 
have more white than southern, but even this is only a question 
of degree in average. 
Nidification. In Assam and N. Burma almost entirely a 
jungle bird; in Central and Lower Burma it frequents the neigh- 
bourhood of human habitations more freely, occasionally building its 
nest in towns and villages. The nest is the neatest and best built 
of any made by Crows, and | have seen specimens made entirely 
of moss and moss roots and so neatly lined with hair and fur that 
they would have been a credit to any bird architect. The eggs 
number four to six and differ from those of intermedius in being 
duller, browner and darker in their general tint and being some- 
what broader in proportion to their length. They average 
43:1x31°6 mm. In Assam and Upper Burma the breeding 
season is during April and May but in Lower Burma and Siam 
January and February are the laying months. 
Habits. These do not differ from those of the other Jungle- 
Crows, but over a considerable portion of their northern range 
they are shy, retiring birds, generally frequenting heavy forest 
and never scavenging round about villages. Each pair has its 
own territory over w hich it hunts and in the breeding season it 
is most destructive to other birds’ eggs and young. ‘It ascends 
the hills up to some 6,000 feet but is not common above this 
height, though it wan ders up to 8,000 or even 9,000 feet. It occurs 
all over the plains except, perhaps, in the driest portions of 
Central Burma.
