Do swans sit on unfertilized eggs?
“The eggs are not fertile. But yearly, [Romeo and Juliet] do lay eggs in the park. Once the eggs are laid, the two female swans do sit on them, then after several weeks they abandon the nest when they realize they won’t hatch,” says Jacquelyn Goddard, spokesperson for the Boston Parks and Recreation Department.
How do swan eggs get fertilized?
Once in the oviduct, the sperm then rapidly swim up the tube into the infundibulum. If there is a ripe ovum there (one that’s just been released from the ovary), the sperm can fertilise the egg and an embryo (a soon to be baby swan) will be formed. The first layer to go onto the swan’s egg is the albumen.
Can swans lay eggs twice a year?
Some swans have been known to successfully breed in their second year, but this is rare.
Do swans sit on their eggs all the time?
How long do swans sit on their eggs? Once all the eggs have been laid, which can take 2-3 weeks, they will all be incubated (ie sat on to start the growth process) at the same time with hatching usually 42 days (6 weeks) later. Is it normal for a swan to sit on her eggs for longer than the normal 6 weeks? Yes.
How do you know if a swan egg is alive?
It should have a smooth, unmarked shell if it is still alive. Shine a bright flashlight through the egg in a dark room, and look closely at the inside. If the egg is alive you will see veins running through it. The process of removing dead or rotten eggs during incubation that uses this method is candling.
How long do baby swans stay in the nest?

Do swans mate with their offspring?
What time of year do swans breed? The mute swan, which is the white swan most commonly seen in the British Isles, will normally mate at anytime from spring through to summer, with the cygnets being born anytime from May through to July.
When do baby swans come out of their eggs?
The definitive end to the incubation is the time when the baby swans appear from their eggs. These hatchlings can take hours to fully break out of the egg shell. As explained in the section, Swans’ Eggs, the shell of the eggs gets progressively thinner and thinner as the embryo develops inside.
What does a swan do during the incubation period?
During this incubation time she will seldom leave the nest or her clutch of eggs, the only times she will do so will be to briefly feed and preen/wash herself. This is another reason why female swans feed so voraciously before the incubation period starts.
How does a swan choose how many eggs to lay?
How the swans ‘choose’ the number of eggs to lay is not known at this time but is likely to be affected by the availability of food, prior condition of the birds, age of the pair and how far advanced into the season the egg laying takes place. See the section, Swans Breeding.
What happens when baby swan leaves the nest?
This staggered hatching would be a disaster – the initial baby swan would need to leave the nest and start to find food, before many of the other eggs were ready to reveal their hatchlings.
