White-throated Flycatcher often quivers the wings and tail after landing on a perch (Stiles and Skutch 1989).
Posturing (wing and tail spreading) has been observed in response to playback on territory. In two closely related species, Alder (Empidonax alnorum) and Willow (Empidonax traillii) flycatchers, Stein (1963) noted tail-flash, a rapid spreading of the tail. White-throated Flycatcher opens the tail and holds it spread out for several seconds upon playback of the song within its territory. There is no information on territory or home range size for White-throated Flycatcher.
Little information. White-throated Flycatcher presumably is at least socially monogamous.
Social and interspecific behavior
Like other species of Empidonax, White-throated Flycatcher typically is solitary.
No reports of predation on White-throated Flycatcher.
