About 1963 or so I read a children's picture book about a large bird, shaped something like a turkey, that acquired the colors of the flowers it ate, and so was able to camouflage itself successfully in the palace gardens. The gardeners were driven to distraction by the depredations of this bird, but always walked right by it as it hid.
Eventually, if I remember right, they cut down all the flowers to deprive it of camouflage, and found the very sad and now colorless bird. At this point everyone realized what an ornament they had lost, and the bird was welcomed back in a renewed garden, more resplendent than ever and no longer forced to hide.
I would like to see this book again, as the watercolor(?) illustrations were memorable.
