The American Redstart is an abundant and widespread warbler in Canada with a breeding range that reaches from British Columbia to Newfoundland and Labrador. The Breeding Bird Survey indicates that the population is currently at about the same level it was in the early 1970s. However, population trends among regions vary widely. 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 May and early June and ends between mid-July and late July, depending on the region. Before or after this period, the probability of an active nest is lower.
 

Conservation and management

Human modification of wintering habitats has likely been partly responsible for observed decreases in the latter half of the twentieth century (Sherry and Holmes 2016). In their winter range, Redstarts consume large numbers of coffee berry borer (Hypothenemus hampei), an economically significant coffee industry pest (Sherry and Holmes 2016). Still abundant and widespread, and with a stable population trend, there are currently few pressing conservation concerns for the American Redstart in Canada.

 

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.
