Brown Teal Decline

 The BrownTeal (Anas chlorotis), or pateke, is a small dabbling duck species endemic to New Zealand distributed throughout the lowland freshwater wetlands and, historically, the Chatham Islands. The brown teal’s omnivorous diet, restricted annual range and mainly terrestrial lifestyle give it a unique ecological niche among waterfowl, somewhat akin to a wetland rodent, and it serves as a classic example of the influence of selective forces that operated on birds in pre-human New Zealand.The Brown Teal (pateke) was once widespread throughout New Zealand but is now rare and restricted to Great Barrier Island and coastal valleys of eastern Northland. The species has suffered an ongoing decline in numbers and range since the late nineteenth century. There are currently between 2000 – 2500 brown teal living in a wild state in New Zealand, making it New Zealand’s rarest waterfowl species on the mainland. The International Union for Conservation of Nature and Natural Resources (IUCN) conservation criteria (IUCN, 1994) list brown teal as “endangered”, and the New Zealand Department of Conservation (DOC) lists it as a “Recovering” species.

The Department of Conservation’s Brown Teal (Pakete) Recovery Plan in 2000 predicted the imminent extinction of the Brown Teal in Northland, and forecasts only medium term brown teal survival on Great Barrier Island without intervention. Responsible for this decline are the traditional factors that have had major impacts on all native New Zealand bird life since the arrival of humans. These include predation from introduced mammals, habitat loss through wetland drainage and estuary reclamation, over exploitation and disease. These factors tend to act together, one factor exacerbating another.  Luckily in 2012 the future for Pateke looks a lot brighter, after some serious effort to halt the decline at the remaining wild sites in Northland and Great Barrier Island, those populations are now considered stable.  With the addition of a captive to wild reintroductions, we have now seen the successful re-establishment of a further 3 self sustaining populations with other sites in progress.
