The State of Winter Wrens
Numbers of Winter Wrens counted during Mountain Birdwatch have been steady since 2000. Sharp drops in numbers occur after harsh winters, but populations have subsequently rebounded in each case.
Data collected by the Breeding Bird Survey indicate no long-term trend in numbers of Winter Wrens. Substantial year-to-year variation is evident, however, and reflects the sensitivity of this species to harsh winter weather.
Opportunities for Conservation
The long-term stability of Winter Wren populations suggests that the species is not in need of any immediate or specific conservation intervention.
What We Can Do to Help
Most importantly, we can continue to provide complex, mature forests that offer safe nesting and wintering habitat. Because of the vulnerability of Winter Wren to harsh winter weather, we should continue monitoring populations, especially given the risk of increasingly volatile and severe winters due to human-caused climate change.
