find a bird which drinks only rain water?

Question

i heard that it will die but would not like to take any other water except rain water

Answer 1

I think it would depend on the quality of the rain water where you live. I have seen birds drink/bathe in rain water and haven't had any dead ones in my yard.

Answer 2

I don't understand your question. No bird survives on water alone. Most birds cannot drink from a pool of water anyway, though doves can.
