The genus ''Empidonax'' is a group of small insect-eating passerine birds in the tyrant flycatcher family, the Tyrannidae. Most of these birds are remarkably similar in plumage: olive on the upper parts with light underparts, eye rings and wing bars. In the nesting season they may be distinguished by range, habitat and call; in other situations, particularly on migration and in winter, it may not be possible to be sure of specific identification. ''Empidonax'' flycatchers often flick their wings and tails rapidly. Euler's flycatcher, ''Lathrotriccus euleri'' and gray-breasted flycatcher, ''Lathrotriccus griseipectus'' were formerly placed in ''Empidonax'', but differ anatomically and biochemically and are now places in the genus ''Lathrotriccus''. ==Species== *Yellow-bellied flycatcher, ''Empidonax flaviventris'' *Acadian flycatcher, ''Empidonax virescens'' *Alder flycatcher, ''Empidonax alnorum'' *Willow flycatcher, ''Empidonax traillii'' *White-throated flycatcher, ''Empidonax albigularis'' *Least flycatcher, ''Empidonax minimus'' *Hammond's flycatcher, ''Empidonax hammondii'' *American gray flycatcher, ''Empidonax wrightii'' *American dusky flycatcher, ''Empidonax oberholseri'' *Pine flycatcher, ''Empidonax affinis'' *Pacific-slope flycatcher, ''Empidonax difficilis'' *Cordilleran flycatcher, ''Empidonax occidentalis'' *Yellowish flycatcher, ''Empidonax flavescens'' *Buff-breasted flycatcher, ''Empidonax fulvifrons'' *Black-capped flycatcher, ''Empidonax atriceps'' ==External links== *(Generic Study of Euler's Flycatcher ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Empidonax」の詳細全文を読む スポンサード リンク
