Summary

Although a common and widespread bird of Canada’s boreal forest, this species remains little known. The Breeding Bird Survey shows little overall change in population since about 1970. With an estimated 99% of the global breeding population, Canada's responsibility for the Philadelphia Vireo is very high. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.

Conservation and management

As a bird of early successional forest on its breeding, migrating and wintering habitats (Moskoff and Robinson 1996), the Philadelphia Vireo is unlikely to face significant habitat shortages in the near future. Philadelphia Vireo have a very restricted wintering range in southern Central America that may become cause for concern, although at present problems are not apparent (Moskoff and Robinson 1996).

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.
