- Uiterlijke kenmerken:
The plumage of adult trumpeter swans is completely white, though their heads and necks are often stained a rusty color from contact with ferrous minerals in the soils of wetland bottoms during feeding. The bill has a red color on the lower madible, legs and feet are typically black But there are 1 in 7 Trumpeters have Leucism in their feet where they lose their black pigment and their feet are either blotched yellowish orange and black or pure orangeish yellow.And the iris is brown.
Identical in appearance, but males typically are larger.
Are Greyish white to light grey tell second winter
Swans are generally aggressive and territorial, particularly while breeding, and each pair should be maintained in a separate pen, away from other swans, geese and large ducks, although the pen may be shared with small ducks, as these are usually ignored by most swan pairs. Fences adjoining other pens should be solid or screened with vegetation to avoid injury from swans trying to fight each other through wire fencing, and should be as tall as the swans themselves, to prevent fighting over the top of the fence.
Good amounts of vegetation should be provided for nest building, with cover available for early-nesting species. Parent hatching and rearing is usual. Swans are able to defend their young against most predators, and their highly-aquatic lifestyle also makes cygnets less vulnerable.

Swans may be best kept on a large area of natural water containing aquatic vegetation, and the surrounding land. For a single pair, a pen of at least 400 square metres is suggested, of which half the area should be water and half grazing land. Banks should be at a shallow angle to allow easy entry to and exit from the water; this is particularly important if cygnets are to be parent reared. More than one pair may be kept in very large parks where each pair can establish a breeding territory. Swans appreciate water weed and grass, but other green foods such as lettuce and cabbage may be used as substitutes if necessary. They are relatively slow eaters and care should be taken in mixed enclosures that they get sufficient food. Natural food should be supplemented with floating pellets.
Trumpeter swans are hardy and their management simple but they should be provided with a large area. They are aggressive to other birds, particularly to other swans and to geese, and can be aggressive to humans, particularly while breeding; however they usually leave smaller ducks alone. They are best maintained in their own enclosure. They may be fed floating pellets, plenty of green food and grass.
These swans breed fairly readily, laying eggs from late April to end of June, on a large pile of vegetation.
Hybridization has been reported with Whooper swan (Cygnus cygnus).
If hand-reared, cygnets should be kept in a brooder with a heat lamp (to give 33,5°C in the first week), with sufficient room for the birds to choose their own comfort zone. Access to water for a swim is appreciated; this may be in an appropriately sized bowl initially (e.g. while the brooder is cleaned out). Starter pellets, chopped green food and for the first few days chopped hard-boiled egg may be given, and grit should be available. If weather permits the cygnets may be kept outside in a pen with a pond by two to three weeks old. It is important to ensure unlimited green food is always available and that the cygnets do start feeding initially, as there is a risk of Starveout.
- Het vrouwtje Trumpeter Swan legt doorgaans zo'n 4-8 dull white eieren het broeden duurt 33-37 dagen.
- Kunstmatig broeden:
De ideale relatieve luchtvochtigheid voor het uitbroeden van de meeste watervogeleieren is 55% voor grondbroeders en 40% bij holenbroeders. De temperatuur is meestal 37,4° C. Stel ventilatie in zoals aanbevolen door de fabrikant van de broedmachine. Eieren moeten minimaal 4 keer per dag automatisch of met de hand worden gedraaid. Naarmate de vrucht zich ontwikkelt, verliest het ei water en wordt de luchtzak groter. Bij normale ontwikkeling van een ei met een incubatietijd van 33-37 dagen neemt de luchtzak ongeveer een derde van het ei in beslag, dit bij drie dagen voor uitkomst. Reinheid is van vitaal belang en idealiter moet de luchtvochtigheid worden verhoogd tot 65% nadat de eerste tekenen van uitkomst zichtbaar worden.
- Aanbevolen passende ringmaat voor de Trumpeter Swan is 27 mm.De gesloten pootring kan alleen aangebracht worden bij een jonge large swan van ongeveer 18 dagen oud.
- It doesn't matter what leg that you band, but it's good to have a consistent system. Suggested: Left leg = Female, Right leg = Male
