Meet the Locals: Pīwakawaka 

Season 3, episode 26: Watch a video about one of New Zealand’s most-loved birds - the fantail or pīwakawaka - and the way they help us test the health of the forest, and whether pest control in the area has worked.
Meet the Locals is a series of mini-documentaries about New Zealand's wildlife, wild places and the people working to protect them.
Each four-minute episode showcases the inspiring work of local communities, businesses and individuals, who make a difference to protecting our natural areas, native species and historic places.
