About the Rajah Scops Owl

The Rajah scops owl (Otus brookii) is a species of owl found on the islands of Borneo and Sumatra. The bird is named after James Brooke, Rajah of Sarawak. Based on patterns of speciation in other endemic montane bird species of the same region, it may potentially have to be split into two distinct species; if so, the name Otus brookii would be restricted to just the Bornean population.

There are two subspecies known from two different islands: O. b. brookii (the type subspecies) found on Borneo and O. b. solokensis found on Sumatra. Taking into account speciation patterns within Otus and general phylogeographic patterns of montane birds on Borneo and Sumatra, both subspecies likely represent two distinct species; taxonomic studies will be required to confirm or deny this claim.

O. b. solokensis has a comparatively large range, being distributed throughout the length of the Barisan Mountains. In contrast, O. b. brookii was formerly only known to have a comparatively small range in the mountains straddling the border of Kalimantan and Sarawak, with a small extension into Sabah. Due to its secretive nature, it had not been sighted since its description... Wikipedia →
