Common Scops-owl Otus scops

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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not 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.

Taxonomic note
Otus scops (Sibley and Monroe 1990, 1993) has been split into O. senegalensis following Dowsett and Forbes-Watson (1993), O. sunia following AOU (1998), O. alius following Rassmussen (1998) and O. scops (with species limits accordingly revised).

Population justification
In Europe, the breeding population is estimated to number 210000-440000 breeding pairs, equating to 630000-1320000 individuals (BirdLife International 2004). Europe forms 50-74% of the global range, so a very preliminary estimate of the global population size is 51000-2640000 individuals, although further validation of this estimate is needed.1000000-3000000 individuals, although further validation of this estimate is needed.

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction.
