The Common Grackle is an abundant and widespread species of open wooded areas in Canada, east of British Columbia. The Breeding Bird Survey indicates that the current population has shown little overall change since about 1970. The species remains abundant; there is currently little need for conservation concern at this time.

Conservation and management

Far more abundant today than in pre-settlement times, the Common Grackle is often considered to be one of the most significant avian agricultural pests of North American croplands (Peer and Bollinger 1997). Control programs likely contributed to the decrease in populations during the 1970s and 1980s (Peer and Bollinger 1997).

 

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.
