The Breeding Bird Survey (BBS) provides the best monitoring data for Western Tanagers in Canada, though it does not provide good coverage of the northern portion of the species' breeding population. BBS results indicate an approximately 100% increase in the abundance of Western Tanager in Canada since the early 1970s. All Bird Conservation Regions for which there are reasonably reliable BBS results are shown below; they all show moderate or large increases. Continentally, the Western Tanager population, as monitored by the North American BBS, also shows an increase since 1970. The species is currently at an acceptable level relative to its national population goal (see Canada graph below).
