Another rare bird species is being welcomed back to Tawharanui this weekend. Up to 30 endangered pateke, or brown teal, will be released into the open sanctuary at Tawharanui Regional Park. The release of these special ducks is took place on Saturday 2 February, World Wetlands Day – a day where government agencies, interest groups and wetlands around the world undertake actions aimed at raising public awareness of wetland values.
