Populations of Hermit Thrush are monitored by the Breeding Bird Survey (BBS) in Canada although the survey covers less than half the breeding population. BBS results indicate a long-term increase of about 50% in numbers since the early 1970s, though the trend is negative in the most recent years (2006-2016). The Christmas Bird Count (CBC) surveys a large portion of the population's wintering range in the southern United States and helps improve coverage though the results include birds that breed in the Unuted States. Continental CBC results suggest that, despite a small increase, there has been relatively little overall change in wintering numbers since the early 1970s. Considering both results, the Hermit Thrush is assessed as having shown a moderate increase in its Canadian population since the 1970s. The species is an acceptable level relative to its national population goal (see BBS Canada graph below).
