New survey shows rock wren hot spots
Rock wrens/tuke live year-round in the harsh alpine environment. No bigger than a silvereye, they are weak flyers and nest on the ground, making them easy prey for rats and stoats.
The Department of Conservation (DOC) began monitoring rock wrens at 22 sites from Fiordland to Kahurangi in 2019 to measure how populations respond to predator control. Two summer surveys have been completed.
DOC lead researcher Tristan Rawlence says results are showing healthy rock wren/tuke populations largely where predators are managed.
“For the first time we’re getting an overall picture of how rock wrens are doing and it’s looking good where predators are controlled, but dire where they’re not.
