Yellow-billed birds found in extreme S range of (and otherwise largely resembling) S. plumbea have been assigned to that species for the best part of two centuries, but were recently shown to represent a distinct species, differing in their yellow vs black bills (3); bluish-grey vs plumbeous-grey plumage in male (1); larger size (effect size for bill height from published data#R 2.49, score 2); distinct habitat (grasslands with greater shrub density on dry and steeply sloping terrain vs grasslands with scattered sub-shrubs associated with mesic environments near poorly drained and flatter soils (1); song like plumbea’s but with clear (whistled) introductory syllables and unique call notes#R (at least 2). Monotypic.
