Note: During all years of the Saskatchewan Breeding Bird Atlas drought conditions persisted and the Atlas range maps for all waterfowl, waterbirds, and wetland-associated species should be viewed as characteristic of distribution and abundance during dry conditions.

Excerpts Adapted from the Birds of Saskatchewan:
Marsh Wrens are difficult to spot as they skulk through reeds and cattails. They are most easily found when one hears their gurgling, rattling trill, a distinctive musical and mechanical mix. Marsh Wrens are summer residents from northeastern British Columbia to Nova Scotia south (often very locally) to central Mexico, with wintering from southwest British Columbia and New Jersey south well into Mexico.
The Marsh Wren nests in deep-water marshes of cattail, bulrush, and common reed-grass. Migrants can sometimes be found in non-marshy areas. For example, in three different years a single Marsh Wren has been caught and banded in fall in the hedgerows of Last Mountain Bird Observatory.
A fairly common transient and summer resident, the Marsh Wren breeds from Kazan Lake and Cumberland House to Luck Lake and Chaplin Marsh in the northern grasslands and in the Cypress Hills-Great Sand Hills area (Smith 1996). Because it prefers extensive deep-water marshes, it is absent, except as an uncommon transient, from large areas in the southern grasslands.
