The Hutton's Vireo is a non-migratory species found in the woodlands of southwestern British Columbia. Results from the Breeding Bird Survey suggest an increasing population since the early 1970s though the sample size is small. There are no major conservation concerns for the species at this time. 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 March and early April 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

The Hutton's Vireo is found in a wide variety of forests with a rich shrub understory (Davis 1995, Campbell et al. 1997), so it is perhaps less sensitive to forest harvest and other disturbances than some species with narrower habitat requirements. Forest management techniques that remove and prevent recovery of shrub understory may be cause for concern for this species. Much of the species' range in British Columbia overlaps with heavily populated and developed areas and although there is no conservation concern at the moment, preservation of forested habitat with a rich shrub understory would be beneficial to maintaining the population (Davidson and Clulow 2015).

 

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)
