It is also known as the Siberian flycatcher or sooty flycatcher, the latter name is also used for the sooty flycatcher of Africa.
Region
East Palearctic and Southeast Asia
Typical Environment
Breeds from Siberia and the Russian Far East through northeastern China, Korea, and parts of northern Japan, favoring coniferous and mixed forests. In the non-breeding season it moves to Southeast Asia, including the Himalayas’ foothills, southern China, Indochina, and the Greater Sunda Islands. It uses forest interiors, edges, clearings, and riparian corridors, often perching in the mid to upper canopy. During winter it readily occupies secondary growth and lightly disturbed woodland.

The dark-sided flycatcher is a small Old World flycatcher that breeds across the East Palearctic and winters in Southeast Asia. It often hunts from a shaded perch, making short sallies to catch insects in mid-air. Also known as the Siberian flycatcher, it shows subtly dusky flanks that give the species its English name. It can be easily overlooked due to its quiet demeanor and soft, high-pitched calls.
