This is an interesting one - normally Jungle Crow has a steep forehead, not one that slopes back smoothly from the bill, like this bird. However, the bill looks rather large for Carrion Crow.
Also, juvenile Jungle Crows sometimes show a sloping forehead.
Not sure which way to call this one. Do you have any more pix?
