How long does it take a baby swan to turn white?

Cygnets are grey when they hatch with black beaks and gradually turn brown over the first six months at which time they learn to fly. By one year old they are predominantly white but the beak remains grey/pink. Full white plumage and orange beak come with maturity. Immature and non-breeding swans moult first.

How can you tell if a swan is male or female?

Usually, you can tell male swans from female swans due to the following: The male will have a larger knob (the bump on the bill) than the female. He will usually be larger, although this appearance can be deceiving if the food supply is not that great. Obviously, with weight loss, the male will also look small.
