Uiterlijke kenmerken:

Male:
Brown eclipse male. Small, flightless, dark brown duck. Mottled dark brown breast. Prominent white eye-patch. Breeding male has glossy green head. Very narrow white collar, flank patch. Breeding males are a dark sepia colour, with strong green iridescence on their head, neck and back, dark chestnut tones on the breast, and lighter plumage on the abdomen, in addition to a conspicuous white ring around the eye and obvious white tail spot. During non-breeding plumage, the iridescence on the head and back becomes less intense, the tail spot becomes indistinct and the eye ring becomes pale fawn.

Notitie:

Captive breeding of the Campbell teals was initially very difficult to achieve, as no studies on the behaviour of the species had been carried out in the wild and "staff [at Mount Bruce] thus had to experiment with a range of techniques to encourage breeding. Success came in 1994 when Daisy, the only wild origin female to ever lay eggs in captivity, finally accepted a mate. Subsequently, breeding has occurred every year – wild origin males contributed genes by pairing with captive raised females."

A tiny population of 25 captive-bred individuals was released on Codfish Island in 1999 and 2000, already intensively managed and pest-free as an important habitat for the critically endangered kakapo. In the final phase of the ecological restoration of Campbell Island (cattle, sheep and cats had already been removed), the world's largest rat eradication campaign was undertaken by helicopter drops of more than 120 tonnes of poisoned bait over the entirety of the island's 11,331 hectare area in 2001; this operation successfully removed what was estimated to be the world's densest population of Norway rats (200,000) from Campbell Island and it was officially declared rat free in 2003. Fifty Campbell teal, a mix of captive-bred and wild-acclimatised animals (from Codfish), were reintroduced to Campbell Island in mid-2004, after an absence of more than a century. Subsequent monitoring in 2005 has shown that the majority of these birds are now thriving in their ancestral homeland. By 2011 the species has firmly been returned to Campbell Island, resulting in a reclassification of its threat status to Endangered.

Breeding:
Het vrouwtje Campbell Teal legt doorgaans zo'n eieren het broeden duurt 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 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 Campbell Teal is 9 mm.
De gesloten pootring kan alleen aangebracht worden bij een jonge small, flightless dabbling duck van ongeveer 10-11 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
