Anna's Hummingbirds are restricted in Canada to the southern coast of British Columbia, though they likely breed occasionally in the southern interior of that province. The species is best monitored by the Christmas Bird Count; numbers on Canadian counts have risen dramatically since 1970, and there has been a large increase throughout its North American range during that time period. This increase has likely occurred in part because of the proliferation of hummingbird feeders which provide a necessary nectar source throughout the year (Clark and Russell 2012).

Conservation and management

The Anna's Hummingbird has greatly expanded its range since the 1930s, moving east and north out of California to cover much of the southwestern United States and the Pacific coast as far north as British Columbia. This expansion is attributed to the increase in non-native flowering trees and shrubs which flower when native species have finished and, at least in urban and suburban areas, the increase in numbers of hummingbird feeders (Clark and Russell 2012). With its expanding population in Canada, there are no conservation concerns for this species.

 

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.
