The Marsh Wren is a common bird in cattail marshes across southern Canada from Quebec to British Columbia and extending through northern Alberta and into the Northwest Territories. Breeding Bird Survey results suggest a large, long-term increase across its breeding range in Canada since about 1970. There are currently few conservation concerns for the species.
Although potentially threatened by loss of marshlands due to drainage and filling, the Marsh Wren readily inhabits man-made marshes and restored prairie potholes (Kroodsma and Verner 2013). Populations overwintering in North America are sometimes subject to heavy snow and freezing temperatures (Kroodsma and Verner 2013).
Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:
