Species of bird
The green-backed flycatcher (Ficedula elisae) is a bird in the family Muscicapidae, which contains the Old World flycatchers.[1] It was long considered to a subspecies of the narcissus flycatcher, but morphological and acoustical differences between the two indicate they are instead separate species.[2] It breeds in northeastern China and winters in southeast Asia.[1]
"F. beijingnica", proposed as a separate species called Beijing flycatcher or Peking flycatcher, is now considered by experts to be the first-summer male of this species and thus no longer a valid taxon.
