You probably already know this but for the others, different species of Bowerbirds have different color preferences! There is some speculation these preferences might relate to their own coloring. Also some speculation this might be due to regional traditions.
The Satin Bowerbird prefers blue, both the male and female have blue eyes and the male has that metallic black (almost blue-looking) feathering that some ravens have.
