Went to Bangladesh on a business trip in Feb. Didn't have much time to go birding but here is what I saw.
Indian House Crow - Corvus splendens
Common Mynah - Acridotheres tristis
Asian Pied Starling - Sturnus contra
Black Drongo - Dicrurus macrocercus
Chesnut tailed starling - Sturnus malabaricus
Oriental Magpie Robin - Copsychus saularii (national bird of Bangladesh)
Indian Pond Heron - Ardeda grayii
Purple Sundbird - Nectarina asiatica
Indian Cormarant - Phalacrocorax fascicollis
Black naped tern - Sterna sumatrana
There were also various egrets and BoP but no bins at the time. I am moving to Bangladesh in the summer so will be able to develop this list more
