The female swan will incubate the eggs and both parents will take care of the young once they are hatched. Young-of-the-year swans are called cygnets pronounced "sig-nets". Cygnets have gray feathers, typically remaining on the head and neck through its first year.
Trumpeter Swan cygnets turn white during their second summer following their molt. At that point, they become "sub adults"- they have white feathers like an adult, but won't reach breeding age until age years. Sub adult swans often remain in groups until they are old enough to form their own pair bonds.

If you saw a large white bird with black wing tips on the underside, you most likely saw a snow goose or pelican. Learn more. Powered by Firespring. Identification and Behavior. This handy, visual reference gives quick and easy steps to identify the swan species you've seen.
Sibley Guides. Advanced Guide to identify Trumpeter vs Tundra Swans. The nest is a huge mound of vegetation, close to the waterside, often among tall fringe vegetation. Swans breed in the Spring, laying an egg every other day, up to a total of 5 to 12 eggs. The female has an area on her underside which becomes completely bare called a brood patch. She will pluck the feathers from this area, using them to line the nest, this allows the eggs to sit closer to her body to keep them warm during incubation.
She will incubate the eggs for days turning the eggs with her bill. The male will keep the eggs warm and protect the nest whilst the female leaves the nest to feed and preen.
The male has no brood patch and are rarely able to incubate the eggs unless the cygnets are almost ready to hatch.
The whole clutch of eggs generally hatches within a hour period, the cygnets remain on the nest for a further 24 hours before entering the water.
The parents pull up weed and stir up sediment from the riverbed for the cygnets. Whilst they are small, the cygnets are often carried on the mothers back. Males will be aggressive, swimming in jerking movements towards intruders, with inner wing feathers arched and neck resting back on shoulders. 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.
Full white plumage and orange beak come with maturity. Immature and non-breeding swans moult first. Breeding females moult next and when the female is completely finished moulting and able to fly again the male then moults. This ensures that one parent can defend the cygnets if necessary. Whilst resting, swans will often tuck one foot up on their back, possibly to dry — this often leads to speculation that they have an injury.
At times the cygnets are reluctant to leave their parents and eventually the parents may turn on them to encourage them to leave, so they can prepare for the next breeding season.
Groups of immature swans and some older birds seeking a new mate or those too old to breed, often congregate in non-breeding flocks. Swans are a protected species under the Wildlife and Countryside Act Swans, their nests and eggs are protected by this legislation and it is illegal to kill, harm or disturb them in any way. If for some reason the eggs are abandoned it is against the law to take the eggs and incubate them artificially. They may only be removed or handled by recognised groups who should act in the best interest of a sick or injured bird.
Should you come across an injured swan, please call the SSPCA or another recognised animal rescue who will be able to assist. As usual — great shots. That one with the two swans and their baby between is just heartwarming. Thank you Terry. Thats very interesting, I have wondered about that. Can you help me out on my family of swans? There are 7, 5 young ones, all very big now, so I cant tell who mom and pop are. The young ones since birth have been 3 greyer colored and 2 white.
Can this be whether they are male or female? They are down by the river right now and still very much grey ones and white ones. Thank you all for your labor and time you dedicate to GMG. I appreciate the little black knob information. Found it as with others, interesting, I feel fortunate to see our swans all season. Can you tell me please: How do I tell the difference in our beautiful sea gulls? They, like the Swans, look very much alike. Thanks in advance. There are many species of gulls but in most, it is much more difficult to tell the difference between male and female, without sexting.
With Herring Gulls, our most common, the bills are very slightly different shaped, but you need to see them side-by-side to compare. Most species of birds have a cloaca, which is a vent on the underside from where they mate, and go pooh. Only a few species, like swans and geese, have any outward genitalia, and it is usually small.
