Rangers in Auckland’s Shakespear Regional Park say stoats are getting smart to age-old trapping techniques, so they have had to come up with new methods, Stuff reports. Senior ranger Matt MaitlandMaitland said the health of bird-life in the park depended on safety, with the park home to bellbird, kākāriki and the North Island tīeke. “Those tīeke have actually been impacted by the stoat here, we have far fewer of them than we did this time last year and it’s quite possible that if we don’t sort this out in a hurry we’ll see a local extinction.”
