Male rock wrens sing songs to attract females for breeding. This bird species tend to mate with only one partner for the whole breeding season. The rock wren nest they build together is very smartly hidden inside a hollow, with only the pebble pathway showing its location.  The female lays five to six eggs in a couple of weeks. When the offspring hatch, both parents nurture and provide for them for the next two weeks at the nest. When the offspring leave the nest, its parents continue to give them food for seven more days. Beyond that, the offspring are no longer reliant on their parents for food, but they may stay around their nest for a further month or so. Pairs are known to raise up to three broods in one breeding season.

What is their conservation status?

Rock wrens are classified under the category of Least Concern species in terms of conservation status. This bird species can be found in abundance in the wild, and their population has grown significantly since 1982. Because almost all of their nesting territory is not disturbed by human activity, there is no risk of human exploitation or disruption. However, cattle foraging near nesting rock wrens may be to blame for an increase in the incidence of nest parasitism. But overall, there is no need for concerted conservation efforts for these birds.
