Identical to males But slightly smallerJuvenile:
Have duller plumage than adults.
- Gedrag:
Aggressive in the breeding season and usually found as pairs or family groups. Flocks of up to 20 birds may be seen in the moulting season, rarely larger flocks. Popular but not particularly common in waterfowl collections.

- Notitie:
Sheldgeese are generally hardy, and mostly aggressive particularly in the breeding season, so that pairs require a separate pen. A pen for a pair of these birds may be 80% grazing land to 20% water, with a minimum size of 200 square metres for the smaller species (e.g. Orinoco goose) and 300 square metres for the larger species.
Grazing birds, their grass should be supplemented with wheat and pellets outside the breeding season and breeders pellets before and during the breeding season. Additional green food should be provided when there is insufficient grass.
Sheltered nest sites may be needed for species which nest early in the year. Ground-level nest boxes, open to the ground, 50x40x40cm, with a ground level entrance hole and containing e.g. dry grass as nesting material.
Orinoco geese are not particularly hardy and require protection in winter, with a good straw bed available even in autumn. Supplementary feeding is important for breeding. They are more social than other sheldgeese but are sometimes aggressive.
These sheldgeese are rarely bred, although pairs which do breed may be prolific. Close ground cover should be provided for nesting, also kennel or wigwam. Broody or artificial incubation is recommended. Goslings very sensitive to cold and damp and should be kept warm, but are otherwise easy to rear; good rearing meal plus duckweed, and live insects suggested.
Hybrids reported with Common shelduck (Tadorna tadorna) and Egyptian goose (Alopochen aegyptiacus).
- Breeding:
- Het vrouwtje Orinoco Goose legt doorgaans zo'n 6-10 pale brownish cream eieren het broeden duurt 28-31 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 28-31 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.
- Ringdagen:
- Aanbevolen passende ringmaat voor de Orinoco Goose is 14 mm.De gesloten pootring kan alleen aangebracht worden bij een jonge goose van ongeveer 12-14 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
