The Hammond's Flycatcher nests in the mature coniferous forests of western Canada. Breeding Bird Survey data indicate a moderate population increase relative to about 1970. Currently, threats on the breeding grounds appear to be minimal. 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 early June and ends between early August and mid-August, depending on the region. Before or after this period, the probability of an active nest is lower.
 

Conservation and management

With an increasing population there appears to be little cause for concern for Hammond's Flycatcher at present, despite the possibility that logging of mature coniferous forests on the breeding and wintering grounds may be detrimental (Sedgwick 1994). The species may not be negatively impacted by climate warming as recent evidence suggests that old growth forest maintains lower spring and summer temperatures possibly shielding climate-sensitive birds from the affects of warming (Betts et al. 2017).

 

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)
