The Yellow-throated Vireo breeds in mature deciduous forest at the southern edges of Ontario, Quebec, Manitoba and the southeastern corner of Saskatchewan. The Breeding Bird Survey indicates the Yellow-throated Vireo has experienced a moderate increase in its Canadian population since about 1970. The species is thought to benefit from the conservation of large tracts of deciduous forest (Rodewald and James 2011). 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 late May and ends in late July, depending on the region. Before or after this period, the probability of an active nest is lower.
 

Conservation and management

Yellow-throated Vireos are associated with edge habitat but are thought to require large stands of mature deciduous trees (Rodewald and James 2011). Thus, the species may be impacted by habitat loss and degradation due to urbanization and changes in land use on both their breeding and wintering grounds (Rodewald and James 2011), similar to many other forest-dependant species.

 

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.
