1. Flock mating/natural pairing of Pateke was the key to the highly successful captive breeding programme – together with the enthusiasm of participants. Flock mating is now being used in a number of rare waterfowl recovery programmes.
2. Captive reared brown teal adapt readily to a wild environment, natural or created.
3. In Northland captive reared Pateke released at Mimiwhangata, Whananaki and Purerua between 1986-1992 survived for long periods and produced offspring – in spite of little predator control, with predator control Pateke are doing well.
4. Where predator control programmes have been in operation at suitably selected quality release sites in Northland (and more recently on the Coromandel) Pateke have survived very well and have successfully reared many progeny.
5. In the absence of waterfowl hunting and predators, captive reared brown teal released into quality Pateke habitat have few problems adapting to the wild.
6. A gradual transition from captive bred to wild, using pre-release pens and a supplementary diet was successful.
7. Brown teal are by far the most predator vulnerable species amongst all species of waterfowl
8. Captive reared teal released on off-shore islands that have suitable predator-free habitat survive and breed well.
9. When the release of captive reared Pateke into quality habitat is coupledwith predator control, a pre-release aviary, supplementary feeding and with the site having an adequate area for a significant population increase (such as at: Mimiwhangata, Purerua and Port Charles), the recovery process is a very simple one!
10. Between 1969-1992 it was learnt that releasing captive reared Pateke at a large number of unsuitable and disconnected habitats, with 35 different sites being used, achieved little, was counterproductive and very expensive.
11. Since the 2000 Audit of the recovery programme steady progress has been made towards increasing the wild populations of Pateke.
• Lack of continuity amongst Pateke management personnel and others directly involved in planning the survival of Pateke.
• Sites used were poorly selected.
• No pre-release study to see if there was an adequate food source.
• No pre-release study to determine whether the habitat was suitable.
• Little predator control and little knowledge of the subject.
• Little understanding about the main predators to control/ eliminate.
• Until early 2000 no sites had ongoing predator control.
• Many sites were out on a limb, with no wild Pateke in the area. • Many sites had no adjacent wetlands for progeny expansion or to which adults could escape.
• Many sites had no loafing facilities or aerial protection.
• Insufficient supplementary feeding of released birds. The value of this is recorded in a paper published in 2013.
• Pre-release aviaries rarely used.
• Competing waterfowl were present.
• Hybridisation with mallards and grey teal occurred.
• Instant dispersal of released birds occurred.
• A lack of ongoing support.
• A lack of monitoring of released birds.
Trapping at Boggy/Wairio in April by Steve Playle resulted in the following critters recorded - 4 cats, 1 ferret, 9 rats, 3 mice, 1 magpie and 17 hedgehogs.
The grand total came to 15 cats, 36 ferrets, 1 stoat, 9 weasels, 130 hedgehogs, 46 rats, 21 mice, 3 magpies, 1 harrier hawk and 1 rabbit.
Steve also saw a Bittern in Boggy Pond down where the culvert pipes are beside the Boggy stop bank. That photo is on the front cover.
Steve has since put in other trap sites along the new track to the viewing hide out by the spillway.
Maybe - but not just yet
