Concentration of Dark-Sided Flycatcher
Dark-Sided Flycatcher has a wide distribution in Asia with northern birds migrating south for the winter. It is also known as the Siberian flycatcher or sooty flycatcher, the latter name is also used for the sooty flycatcher (M. infuscata) of Africa.
Structure of Dark-Sided Flycatcher
Dark-Sided Flycatcher is 13 to 14 cm long. The upperparts are plain and dark grey-brown apart from a pale wingbar and pale edging to the tertial feathers. The breast and flanks have a variable amount of streaky dark grey-brown. This is unlike the similar Asian brown flycatcher which has rather plain pale under parts and the grey-streaked flycatcher which is white below with distinct grey streaks. Dark-Sided Flycatchers have a pale sub-moustachial stripe and a dark malar stripe which outlines the white throat and half-collar. The centre of the lower breast and belly is white while the under-tail coverts are white with dark centres to the feathers. The bill is short and dark and the feet are black. The eye is large and has a whitish ring around it. The wings are long with a longer primary projection than the Asian brown flycatcher. The adult Dark-Sided Flycatchers of both sexes are alike but juveniles have pale spots on the upperparts, a mottled breast and buff tips to the wing-coverts.
