In this video, the head of the University of Otago's Threatened Birds Research Group, Associate Professor Ian Jamieson, explains the results of a study on the effects of modern aerial 1080 methods on a marked population of native robins.

Using the Animal Health Board's 1080 operation in Silver Peaks, the study found that:

• The pre-fed 1080 operation had no negative effect on robins
• It reduced the possum and rat numbers to almost zero
• Robins experienced relatively high breeding success when predator numbers were low
