Actually, this is just a genetic coloration. All mute swans are taxonomically labeled as Mute Swans (Cygnus olor). However, centuries ago, someone tried to produce an albino colored swan. They did not succeed. A leucistic (variation) was derived which produced a whiter version in which the feet are lighter colored and the beak more orange than reddish orange. Cygnets are white in color.

This swan was labeled a Polish Mute Swan. At one time, they thought it was a different species and labeled it Cygnus immutabalis, meaning the changeless swan. However, taxonomists realized that it was not a different species only a leucistic coloration. Through the years, and many flocks later, this leucistic coloration still appears in both wild and captive settings as it is genetic in nature.

Your male swan is known as a Royal Mute in that it has the normal coloration of black feet, reddish orange beak and the cygnets are taupe in color when hatched, but later turn white. We hope this information is of benefit. The Regal Swan
