White-winged Crossbills are widespread and abundant across the spruce forests of Canada. Their local numbers fluctuate widely from year to year depending on the spruce cone crop, since these birds feed almost exclusively on spruce seeds. Results generated by the Christmas Bird Count show wide interannual variation, but little overall change relative to the early 1970s. 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

Population size of the White-winged Crossbill fluctuates widely in response to food availability (spruce seed; Benkman 2012). Therefore, large-scale forestry that reduces the age-class distribution of spruce forests enough to limit cone production could be detrimental to this species (Benkman 2012).

 

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.
