The American Robin is often viewed as the quintessential migratory bird heralding the arrival of spring. However, many actually remain in southern Canada throughout winter, congregating in flocks and feeding on berries in woodlots.

American Robin
The American Robin is among the most widespread and abundant birds in Canada, breeding almost everywhere south of the high Arctic, and wintering from southern Canada to Mexico. There are approximately 170 million individuals in Canada, representing 46% of the global population and a moderate degree of responsibility for Canada. Another 30 million individuals breed in Alaska and migrate to or through Canada, boosting the total proportion that occurs in Canada to 53%, which corresponds with high responsibility. The Canadian population of American Robin has shown little change relative to 1970 based on the Breeding Bird Survey. Confidence in this assessment is high given that coverage and precision are good, and the trend is also supported by the Christmas Bird Count. The national population of American Robin is within its goal range.
The Canadian population of American Robin is best monitored by the Breeding Bird Survey (BBS), which is well-suited to detecting the species and has high precision, although coverage of the northern parts of the breeding range is limited. The national trend increased from the early 1970s to late 1990s, declined rapidly until around 2005, and has remained largely stable ever since, around 12% above early 1970s levels. There has been a moderate decrease in the Maritimes and a large increase in the southern Prairies, but little long-term change in all other regions. The continental Christmas Bird Count (CBC) provides good coverage of American Robin in winter, and as nearly half of the population breeds in Canada, can also provide insights into Canadian trends. It also shows little change relative to 1970, allowing for high overall confidence in that status. The Canadian CBC shows an increase, however this likely reflects an increased percentage of birds overwintering in Canada rather than a growth in the population.
The goal for American Robin is to remain at or above its average population level from 1970 to 2022, based on the Breeding Bird Survey. Recent data show that the population is within its goal range.
