- Bubo coromandus klossii described by Herbert C. Robinson in 1911 was an adult dark brown male eagle-owl collected in north Perak, Malaysia.[5] This subspecies is thought to occur in Southeast Asia.[4][6]

Distribution and habitat
The dusky eagle-owl occurs from Pakistan, India, Nepal and Bangladesh to Myanmar, Thailand, Malaysia into China.[1] In Peninsular Malaysia, it has been recorded in oil palm plantations during surveys carried out between autumn 2009 and 2010 in the states of Selangor, Perak, Pahang and Negeri Sembilan.[8]
Its preferred habitats are wetlands with dense tree cover.[7][9]

The dusky eagle-owl is usually active at night and emerges from its roost shortly before sunset. In cloudy weather, it sometimes also hunts during the day.[7]
The nesting season is from November to April.[citation needed] The nest is made of sticks in the fork of the trunk of a large tree preferably near water and often in the vicinity of human habitation.[citation needed]
