The Yellow Warbler breeds in willow and shrubby thickets and woods especially in riparian areas, with an extensive range that reaches across Canada from Newfoundland and Labrador to the Yukon Territory and the west coast. The Breeding Bird Survey indicates the national population has decreased since the early 1970s. Changes in riparian habitat as a result of climate change are a potential concern for the Yellow Warbler (Giermakowski et al. 2016). 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 mid-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

The Yellow Warbler is commonly found in early successional riparian areas dominated by willow species (Lowther et al. 1999). Despite the apparent decrease in population, there are currently few conservation concerns in Canada for this widespread and still very abundant species. However, climate change may be a concern in the future; climate models have predicted a change in water availability and riparian areas within the next 100 years, resulting in changes to riparian habitats and permanent water (Giermakowski et al. 2016).

 

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)
