The Pine Warbler is an uncommon inhabitant of Canada's forests, restricted primarily to the southern third of Ontario, with smaller populations in extreme southeastern Manitoba and southern Quebec and New Brunswick. The Breeding Bird Survey suggests a large increase in population relative to about 1970. This increase may be due in part to expansion and maturation of pine plantations. There are currently few conservation concerns for the species.

General nesting period in Canada

Nesting period starts between late May and early June and ends in early August, depending on the region. Before or after this period, the probability of an active nest is lower.
 

Conservation and management

Despite apparent habitat loss and degradation of native pine forests throughout its range, populations of this species have increased (Rodewald et al. 2013), and the species has benefitted from pine plantations. Population growth in Canada is currently strong and there are few known conservation concerns.

 

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.
