Taxonomic note
Sturnella magna (Sibley and Monroe 1990, 1993) and S. lilianae (Sibley and Monroe 1990, 1993) have been lumped as S. magna following AOU (1998), who note the two groups differ in plumage, morphology, and habitat preferences (Lanyon 1962; Rohwer 1972, 1976), but are quite similar in vocalizations (Lanyon 1962).

Population justification: Partners in Flight (2019) estimate the global population size to be 37,000,000 mature individuals.
Trend justification:
Partners in Flight (2019) currently estimate that S. magma is undergoing annual population declines of ~3.26% throughout its range, which equates to a ~24.2% decline across the stipulated ten-year period. Such trends are supported by data from the Breeding Bird Survey, that estimates annual declines of ~3.31%, a ~28.6% decline over ten years (Sauer et al. 2017), and the Christmas Bird Count, that suggests a 3.24% rate of annual decline in the USA, ~28.1% across ten years (Meehan et al. 2018). Whilst the Breeding Bird Survey and Christmas Bird Count only refer to trends in the USA/Canada and USA respectively, Partners in Flight provide estimates for S. magna's wider population and in the absence of specific trend data from elsewhere in its range, declines are tentatively place in the range 20-29% over the stipulated ten-year period. If population declines are evidenced to be higher throughout its non-North American range however, such rates of decline would need to be placed in a higher band.
