The Northern Waterthrush is an abundant warbler of Canada's northern forest bogs, swamps and riparian habitats, with a breeding range reaching from the east to the west coast. The Breeding Bird Survey suggests that populations have increased since about 1970, but poor coverage of the northern portion of the breeding range reduces the reliability of this result.

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

Currently, there are no known major conservation concerns for the Northern Waterthrush. While the northern breeding habitats appear to be fairly secure, loss of mangrove swamps on the wintering grounds is becoming an increasing concern (Whitaker and Eaton 2014).

 

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.
