This is a polytypic species[1] consisting of 10 subspecies.

  • S. s. furax in the lowlands of southwestern Costa Rica and western Panama
  • S. s. isthmicus in Panama (except western Chiriquí and Darién)
  • S. s. scotinus on Isla Coiba and Isla Ranchería (off western Panama)
  • S. s. melicus on Isla Taboga (Bay of Panama)
  • S. s. speratus on Pearl Islands (San Miguel, Saboga and Viveros)
  • S. s. striatipectus in eastern Panama (Darién) and Colombia west of the Andes (south to Cauca)
  • S. s. perstriatus from northeastern Colombia to mountains of northern Venezuela; Trinidad
  • S. s. flavidicollis in southwestern Colombia (Nariño) to arid western Ecuador and northwestern Peru (Piura)
  • S. s. immaculatus in arid coastal Peru (Lambayeque to Ica)
  • S. s. peruvianus in northern Peru (upper Marañón Valley in Cajamarca and La Libertad)

The different races may involve more than one species, further study is needed. A population in southwest Ecuador may represent another undescribed subspecies.
