Researchers found that aerial 1080, applied in the Silver Peaks region in Otago, shows that the pre-fed 1080 operation at Silver Peaks had no negative effect on the robins, 1080 knocked the possum and rat numbers down to almost zero, and robins’ experienced relatively high breeding success when predator numbers were low.

Silver Peaks (Aerially applied 1080 site)

• All banded birds alive 16 days after the 1080 operation
• 67 per cent of monitored nests at the site successfully produced at least one fledgling.

Silversteam (control site)

• All monitored birds in the control site were re-sighted
• Only 8 per cent of monitored nests successfully producing at least one fledgling.
