Rock wren conservation

Rock wrens are our only true alpine bird. It is unknown how they survive the harsh climate above the tree line all year round, but it is likely they continue to forage on rocky bluffs where snow has not collected and amongst large boulder fields. Some have suggested they may have a period of semi-hibernation.

Stoats are main predators

Rock wrens are poor fliers. They nest on the ground and are easy targets for introduced predators.

Until recently, it was assumed rock wrens were relatively safe from predators in their alpine habitat. However, rock wrens are now absent or very rarely seen in many areas where they were once commonly found.
Researchers using nest-cameras have identified stoats as the main predator of rock wrens.
