JAYBIRD - Blue Jay drinks from a tree limb scar. When theories of protective coloration were first being debated around 1900, birds like the Blue Jay were a puzzle. It was difficult to imagine how such flashy colors could be helpful for concealment. We now know that color patterns evolve for many reasons, not just for camouflage. The Jays' flashy color patterns may make it harder for a predator to recognize the bird and tell what direction it is looking.
