CBAC Rock Wren
Rock Wren/ Pīwauwau are New Zealands only true alpine bird that lives above the bushline year round. Rock Wren are extremely resilient in hostile alpine conditions, their nests can be as warm as 30 degrees despite below freezing temperatures.
Despite this, Rock Wren are extremely threatened by predators. In areas where there is predator control, around 85% of nests are successful in fledging young. In areas where there is no predator control, nesting success is 0 – 30% and populations are at risk of extinction.
The Rock Wren population is unknown but they are nationally endangered.
