Concentration of Dark-Sided Flycatcher

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.
Songs of Dark-Sided Flycatcher
