One of the Spruce Grouse's primary defenses against predators is the disruptive coloration of its plummage, tricking the eye and enabling the bird's shape to blend with its surroundings. In addition to this camouflage, the grouse instinctively stops, remaining perfectly still in the presence of a predator. This behavior makes them very hard to see!
Above a male walks alertly toward the forest, and below a female sits motionless under a spruce. If you did not know she was there, she would disappear, blending completely into the browns and grays around her.
