The Mountain Serpent Eagles (Spilornis kinabaluensis) are endangered birds of prey that are found in northern Borneo, Sabah, Sarawak and Kalimantan, where they inhabit submontane and montane evergreen rainforests.
For example, they occur within the Kinabalu National Park and the Mulu National Park.
They appear to prefer forests that are 1,000-2,900 meters above sea level, and their high-altitude habitats are usually too remote for logging and agriculture, offering them a safe haven in those areas, as their numbers are endangered at lower attitudes due to deforestation.
They also like to be separated vertically away from Crested Serpent-eagles (Spilornis cheela) by a few hundred meters in those areas where they both occur.
