No. 1 is a young bird, No. 2 a male in full breeding plumage, 

 and No. 3 a bird of the year in quite immature plumage with a wing 

 well under 8 in. It might possibly be a young specimen of bacchus.

A. bacchus and A. grjyi are, of course, species and not 

 sub-species, and they breed together over a great portion of their 

 joint habitat, i.e., from Assam eastwards, and very often in company 

 on the same clump of bamboos or trees. On account of this young 

 birds are very often hard to determine, and this is the case with 

 the third bird I have named A. gr tyi. but which may possibly be 

 the present species.

This is a heron with a very wide range from Travancore in 

 Southern India, throughout that country wherever suitable, and 

 throughout Burma, Siam and the Malay Peninsula, but nowhere is 

 it at all well known, less because of its rarity than on account of its 

 skulking shy habits. In Assam when beating for buffalo we used 

 sometimes to put this bird up, bat in bright sunlight it was as 

 unhappy and uncomfortable as an owl.
