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.
