Striped Owl (Asio clamator)


French: Hibou strié German: Schreieule Spanish: Búho gritón

Bubo Clamator


, 1808,



Formerly placed in monotypic genus Rhinoptynx, which was later normally subsumed within Pseudoscops; seems, however, to be very closely related to other Asio species, this supported by recent DNA studies, in which found to be sister to A. otus#R. Race forbesi sometimes merged with nominate; very poorly known race oberi sometimes synonymized with nominate#R. Four subspecies currently recognized.

Subspecies and Distribution
  • A. c. forbesi (Lowery & Dalquest, 1951) – S Mexico to Panama.
  • A. c. clamator (Vieillot, 1808) – Colombia and Venezuela to the Guianas, S to E Peru and C & NE Brazil.
  • A. c. oberi (E. H. Kelso, 1936) – Tobago#R and NE Trinidad (possibly extinct from latter).
  • A. c. midas (Schlegel, 1863) – E Bolivia and S Brazil S to NE Argentina (to Buenos Aires) and Uruguay.
  • In addition, an unnamed subspecies has been found on W slope in Ecuador and Peru#R.
