The Breeding Bird Survey (BBS) is the most reliable source of data for the American Robin and indicates a stable population relative to about 1970, both at the national and continental level. Though the BBS does not provide good coverage of the species' large northern range, the various provincial breeding bird atlases provide information for that area. The recent Maritimes atlas (Whittam 2015) suggests little change in the probability of observations, while preliminary results from the Atlas of the Breeding Birds of Quebec 2017 suggest an increase in observations between the two atlas periods, though this may be due to increased effort in the second atlas. The British Columbia atlas suggests no change in distribution (Starzomski 2015). The second Atlas of the Breeding Birds of Ontario (see table below) suggests a large increase in detections between the two atlas periods. Considering all information, the American Robin is best assessed as having shown little overall change in population since the 1970s. The American Robin is at an acceptable level relative to its national population goal (see Canada graph below).
