Notitie:

Dabbling Ducks are generally hardy, easy to maintain and easy to breed. Shelter may be required by some of the smaller species in winter. They should be provided with cover (including marginal pond cover) and loafing areas as well as water. A pen which is 50% water is suggested. The water may be shallow (i.e. no more than two feet deep is required), and muddy areas for dabbling in are also appreciated. These ducks are generally good in mixed collections, although the smaller and quieter species may be bullied. Territorial disputes between ducks of the same species may be avoided by keeping only one pair of each species in an enclosure, unless the area is very large. For a single pair of ducks a pen are of 50 to 100 square metres, depending on the size of duck, should be provided.

A diet based on wheat and pellets is suggested, with maintenance pellets changed to breeders pellets for the breeding season. Bread and greenfood are also appreciated. Grit should always be available, with soluble grit (e.g. oystershell grit) as a calcium source when breeding.

Most species are ground nesters and both close ground cover and ground level nest boxes should be provided. Hand-rearing is generally preferred, as these ducks are generally poor parents in captive conditions, particularly in enclosures shared with other waterfowl. These ducks are prone to hybridization, particularly with closely related species, which should be kept apart from one another.

Garganey are hardy, but shelters and/or good ground cover should be provided for protection in prolonged /severe frost. These ducks are easy to manage, and suitable for mixed collections but are quiet and may be bullied. Feed as other Dabbling Ducks: wheat, pellets, greenfood, grass.

These ducks are shy and somewhat difficult to breed. Dense cover and seclusion, without competition, should be provided. Nest in areas of grass or low-growing plants at a distance from water, lay April to May, with replacement clutches sometimes laid as late as June if the eggs are removed. They are very sensitive to disturbance while sitting and broody or artificial incubation is suggested. Ducklings are not difficult to rear; they start feeding easily, but need care and protection when young. Starter crumbs with greenfood such as duckweed may be fed.

This species may hybridise with Anas species, Aythya species; they should be kept separated from the closely-related Blue-winged teal (Anas discors) and Cinnamon teal (Anas cyanoptera). Hybrids also reported with Wood duck (Aix sponsa).

Breeding:
Het vrouwtje Garganey legt doorgaans zo'n 7-9 cream to pale coffee eieren het broeden duurt 21-25 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 21-25 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 Garganey is 7 mm.
De gesloten pootring kan alleen aangebracht worden bij een jonge small dabbling duck van ongeveer 10 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
