Similar Species

  • Eastern Wood-Pewee is browner, has no or only weak eyering, and has dirty smudging under the tail.
  • Difficult to distinguish from other Empidonax flycatchers (especially Willow and Alder), but is the greenest of the North American Empidonax, and also among the largest. It also has a paler face that does not contrast much with throat, and has a longer primary projection.
  • In fall can be confused with Yellow-bellied Flycatcher because of yellowish on throat and underparts. Yellow-bellied has shorter bill and tail, and the throat is more grayish yellow (compared with clear yellow in acadian).
