The Green-winged Teal is a widely distributed and relatively abundant species in Canada. Unlike that of many other dabbling ducks, this species’ core breeding range is not in the Prairie Pothole Region, but rather in the boreal forest. In western Canada, Green-winged Teal numbers have increased steadily since the early 1990s, whereas in eastern Canada, they have remained relatively stable over the same period. The Green-winged Teal is the most hunted duck species in Canada after the Mallard and the Black Duck, although the harvest level has been declining steadily since the 1960s. Most of the Canadian harvest takes place in Ontario and Quebec, and represents only a fraction of the continental harvest. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.

General nesting period in Canada

Nesting period starts between late April and late May and ends between late June and late July, depending on the region. Before or after this period, the probability of an active nest is lower.
 

Conservation and management

Green-winged Teal are numerous and their population has increased over recent decades. Unlike other dabbling ducks, an important segment of the Green-winged Teal population breeds in the boreal forest, which buffer this species from habitat losses farther south caused by agricultural and urban development.

 

 

Bird conservation region strategies

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:

  • conservation concerns (i.e., species vulnerable due to population size, distribution, population trend, abundance, or threats)
  • stewardship responsibilities (i.e., species that typify the regional avifauna or have a large proportion of their range or population in the sub-region)
  • management concerns (i.e., species that require ongoing management because of their socio-economic importance as game species, or because of their impacts on other species or habitats)
  • other concerns (i.e., species deemed a priority by regional experts for other reasons than those listed above or because they are listed as species at risk or concern at the provincial level)

Select any of the sub-regions below to view the BCR strategy for additional details.
