The male ruddy duck’s bubble display is a unique courtship behavior where he raises his stiff, bright-blue bill slightly above the water and rapidly beats his chest with it, creating a rush of bubbles and ripples around him. This display is paired with tail feathers held high, showcasing his striking colors and drawing attention to potential mates. It’s a lively and energetic performance, often accompanied by a soft drumming sound as his chest hits the water.
