Is the young Mute Swan at Niles Pond a male or female? Based on outward appearances, the simple answer is we don’t know yet. Notice that there is no pronounced black knob, or protuberance, at the base of the young swan’s bill. Our young swan only hatched in the spring of this year and has not reached puberty. The knob becomes prominent at about three years of age.
After swans reach maturity, it is easier to distinguish between the two sexes when they are side by side. The male’s knob, also called a blackberry, is larger than the female’s blackberry, and too, his neck is thicker.
In case you were wondering, the swan’s bill will begin to change color at eight to ten months and it will not turn completely orange until the swan is at least one year old.
Compare the difference between the male and female swan in the photo above. Mr. Swan, on the left, has a larger blackberry, thicker neck, brighter orange bill, and is overall larger. He is with is his second mate, Mrs. Swan, and the last cygnet they hatched together.
