The Warbling Vireo is an abundant bird in Canada's deciduous riparian forests, ranging from the Maritime Provinces to the west coast and north into the Yukon and the Northwest Territories. Breeding Bird Survey results demonstrate that the population in Canada has increased by some 47% since the early 1970s. The species is likely more common today than during historic times, having benefited from forest clearing during the 1800s and 1900s settlement period (James 2007a).
An abundant species with demonstrated population increases across the country, there are currently few conservation concerns in Canada for this species. In Ontario and Quebec, the Warbling Vireo may have benefited from clearing of coniferous forest, which created habitat by leaving large deciduous trees near open spaces (Gardali and Ballard 2000). However, the species may be vulnerable to loss of undisturbed deciduous forest habitat on the wintering grounds (Hutto 1989).
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:
