I heard turacos are the only birds which have natural green and red pigments in their feathers and that if you soak a feather in a glass of water, the water turns pink! I would like to see myself if it's true
I don't know, it's just what I read on many sites and that's why I was so curious to try. And about the rain... It is often assumed that this coloration will wash out when the birds are bathing or after heavy rains, but this is true only if the water used for bathing happens to be very alkaline.
