Female Red-Breasted Merganser
The Red-breasted Merganser is broadly distributed throughout Canada, and is known to breed at latitudes up to 75o N. It is thought to be one of the least abundant sea ducks in Canada. The national population is thought to be increasing. However, its population status and numbers are difficult to accurately determine or estimate since aerial surveys do not always distinguish between the three species of mergansers. The secretive nature of the Red-breasted Merganser, the remoteness of some of its breeding range, and tree cavity-nesting habits also complicate the monitoring of this species. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
