The cassowary's blue neck is primarily due to the presence of specialized skin cells called chromatophores, which contain pigments that reflect light in a way that produces vibrant colors. This striking coloration is thought to play a role in communication and mating displays, signaling health and vitality to potential mates. Additionally, the blue hue can help the bird regulate its body temperature in its tropical habitat.
