The Red-naped Sapsucker breeds in the mixed forests of western Canada, with the highest density in British Columbia. Results from the Breeding Bird Survey show strong fluctuations in numbers, but the overall trend in Canada is a moderate increase in the population relative to about 1970. 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 mid-July, depending on the region. Before or after this period, the probability of an active nest is lower.
 

Conservation and management

Though populations appear to be increasing overall, the Red-naped Sapsucker has been negatively affected by the cutting of nest trees, especially aspens, in parts of the species' range (Walters et al. 2014). Habitat degradation of riparian areas reduced available habitat in some areas of the northwestern Great Basin (Walters et al. 2014), which may explain the negative population trends in this region.

 

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)
