Re: [nafex] Saving cherries from the birds (Good Fruit Grower)

Most fruit eating birds see into the ultraviolet and hence colors that we cannot see. I believe that your black decoys are truly black and lacking any appropriate ultraviolet component. The red color is further away from the ultraviolet that is probably present on the black fruit. There was a nice article in Scientific American magazine many years ago addressing bird sight. I'm sorry but I no longer have the article nor could find a reference for you.

I can kind of see why
black doesn't work. Red is a strong color that
stands out in nature so that birds would be
attracted to the color, as
it indicates
ripeness. Birds may not be attracted to the color per se of

black berries, as lots of things are very
dark colored in nature.
