Justification of Red List Category
This species is listed as Near Threatened because, although it is very poorly known, there are some indications that its very small range supports a moderately small, fragmented population, which may be undergoing a continuing decline owing to forest degradation. Further information may indicate it is more threatened.
The global population size has not been quantified, but the species is described as rather frequent (Konig et al. 1999).
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
Otus umbra is endemic to Simeulue Island, off north-west Sumatra, Indonesia (BirdLife International 2001). Reports as to its status differ, from rare, or possibly rare, to not uncommon.
This species favours forest edge and remnants, especially on coasts, as well as clove plantations.
Forest destruction in the Sundaic lowlands of Indonesia has been very extensive, but very few data on this phenomenon are available from Simeulue. The tolerance of secondary and edge habitats shown by this species renders it unlikely to be under immediate threat.
