Genetic data#R indicate that this species may be closest to S. nigricans. Smaller size of race grisea striking, and suggests a species-rank difference, but otherwise distinguished in plumage only by its whiter chin and throat; recordings of grisea appear to be lacking; further work required. Two subspecies recognized.

Subspecies and Distribution
  • S. c. grisea Lawrence, 1871 – Costa Rica and W Panama (E to Veraguas).
  • S. c. cinerea (Tschudi, 1844) – Andean slopes and foothills from Colombia (including Santa Marta Mts and Sierra de Perijá) and Venezuela (Trujillo) S to Bolivia (W Santa Cruz).
