Link to BirdLife species factsheet for Campbell Islands Teal

Campbell Islands Teal Anas nesiotis was formally recognised by BirdLife International in 2000 and immediately listed as Critically Endangered under criterion D1, as it had a population of fewer than 50 mature individuals.

Since 1999, a breeding, translocation and reintroduction programme has been successful in increasing the total population (captive and wild) to over 200 individuals (Potter 2006) on Campbell Island and Codfish Island at least. Based on the results of the programme, it is thought that by the 2011 Red List update, the species’s wild population will have exceeded the threshold of 50 mature individuals for at least five years.

It is therefore proposed that the species be downlisted to Endangered under criterion D1, on the basis that the population still numbers fewer than 250 mature individuals. Comments on this proposal would be welcomed.

  1. While no accurate count of the teal is avaiable due to the isolation and rugged nature of their 2 island habitats (Campbell and Whenua Hou/Codfish Islands) a survey in 2008 and opprotunistic observations on Campbell show that the 155 birds released between 2004 and 2006 have bred and spread around the suitable areas of the island. The Deaprtment of Conservation considers that the reintrouced population has now established and the populations are safe from internal threats ie they are still at risk form introduced predators, disease etc. As such I’d support the down grading of the threat status for this species. It is hopefull/ likely that the populations will exceed 250 mature individuals in the near future but, given their limited distribution and vulnerability they will always be at risk form external threats.
