The American Kestrel is best monitored in Canada by the Breeding Bird Survey (BBS), despite incomplete coverage of the species' northern breeding range. BBS results show a relatively steady decline in the population over the course of the survey, with an overall decrease of about 54% of the population between 1970 and 2016. The decline is consistent throughout the Bird Conservation Regions (BCRs; results for all BCRs with reasonably reliable results are displayed below) but varies from about a 33% overall decline in the Atlantic Northern Forest to as high as 77% in the Northern Rockies. Because the American Kestrel was affected by DDT and persecution (Farmer et al. 2008), resulting in low levels of abundance at the start of monitoring efforts, and its historical abundance remains unknown, a specific management goal relative to 1970 has not yet been set. However, because the population has continued to decline, it is clear that it is below the lowest acceptable level relative to its national population goal (see Canada graph below).
