Why do mute swans have an orange-red beak with a black knob?

The mute swan's orange-red beak features a distinctive black basal knob, which is larger in males and used to assess dominance and mate quality. The coloration comes from carotenoid pigments and melanin. During breeding season, the knob swells noticeably, signaling hormonal activity and reproductive fitness to potential partners.
