- L. specularioides specularioides - Patagonian crested duck
- Notitie:
Breeding birds are territorial and both sexes are very aggressive, chasing conspecifics and other, often larger, wildfowl species. Pair bonds are strong, and mates cooperate in caring for ducklings. High levels of vigilance, co-operation by both adults and aggressiveness allow Crested Ducks to nest in close proximity with predatory birds. Many of the displays of this species are conspicuous and striking, and females have loud calls. Male courtship displays have pronounced orientation components with respect to the target female. The long tail is often conspicuously raised, exposing the black undertail coverts, and the male's crest is often erected during displays.
Preferred nesting habitat is on the ground in tall grass or shrubbery on small islets or lake shores, but occasionally further away from water. The nest is built by a solitary pair and is made up of vegetation and lined with their soft breast feathers. A double brood is quite common. Incubation is undertaken by the female only.
- Breeding:
- Het vrouwtje Patagonian crested duck legt doorgaans zo'n 5-8 cream to pale coffee eieren het broeden duurt 30 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 30 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 Patagonian crested duck is 12 mm.De gesloten pootring kan alleen aangebracht worden bij een jonge dabbling duck 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
