Field Marks and
Identifying Characteristics:
I first heard an unfamiliar call, but then recognised it as matching the calls of a Least Flycatcher I had heard described,so I pulled out my Tablet with iBird Pro on it and played Least Flycatcher calls,and it was a perfect match. I then went into the cottonwood grove and played the call,and the bird came in and I got great looks. Small olive flycatcher with a white throat and short bill
(see photos)
Song or call & method of delivery: Constant "chip-ik" call heard
(video of audible call)
Behavior: Actively flycatching and calling in the lower canopy
Habitat: Dense Cottonwood grove along the Green River
Similar species and how
were they eliminated:
No other Empidonax makes the same or similar calls,so the ID was straight forward
Previous experience with
this & similar species:
Yes,saw an apparent Least Flycatcher at Lytle Ranch in May of this year,and at Welcome Wash along the Beaver-dam slope in May of last year. Both of those sightings, the bird was not calling so I made my ID on visual characteristic,which are not absolutely reliable with Empidonaxs so I did not submit a record to the committee out of personal doubt. No doubt this time
