Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AVES STRIGIFORMES STRIGIDAE

Scientific Name: Otus spilocephalus
Species Authority: (Blyth, 1846)
Common Name(s):
English Mountain Scops-owl, Mountain Scops Owl, Mountain Scops-Owl
Taxonomic Notes: Otus stresemanni was formerly considered a distinct species following Marshall (1978), and it was treated as such in Collar and Andrew (1988). It has subsequently been treated as a subspecies of O. spilocephalus following Sibley and Monroe (1990, 1993), but this treatment is under review by the BTWG.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Ekstrom, J., Butchart, S., Harding, M.
Justification:
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
