The Bufflehead is the smallest of the Canadian diving ducks. Buffleheads occur from coast to coast, but are more abundant in western regions of Canada. The species uses tree cavities for nesting. Overall, the Canadian population has been increasing since the 1970’s. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
Since the population is increasing there are limited management concerns for this species. However, the bufflehead breeding distribution is influenced by the distribution and availability of nesting cavities. Loss of cavity-bearing trees, particularly in the Aspen Parkland due to agricultural expansion and in the boreal forest due to logging, is potentially of concern (Sea Duck Joint Venture Management Board 2008). In Canada, the number of Buffleheads harvested has declined in correspondence with a general decline in the number of waterfowl hunters.
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:
