Widespread and abundant across the southern United States, the Northern Mockingbird reaches its northern limits in Canada, primarily in southern Ontario, Quebec, and Manitoba, and the Maritimes. Breeding Bird Survey results suggest little overall change in the population since the early 1970s, though the sample size is relatively small.

General nesting period in Canada

Nesting period starts between late April and late May 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

Once captured and sold as cage birds to markets in the United States and Europe during the 1800s, populations of the Northern Mockingbird were greatly reduced in many parts of its range (Farnsworth et al. 2011). However, in recent decades, changes to the human-altered landscape, such as creation of fields and planting of ornamental shrubs and trees, have provided breeding and wintering habitat and facilitated range expansion (Farnsworth et al. 2011). There appear to be few current threats to the 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.
