(Description:) Field Marks and Identifying Characteristics:	Confirmed by call - no visual. Call was compared to recording on iPhone app. - "iBird Pro". The call sounded like the bird's name "whip-poor-will" with the last notes faster in succession than the first. I was pretty shocked to hear the call along the Green River, but am positive that's what it was. After I heard it, I played the call on my ipho ne (iBird app) to make sure as well, and its pretty unmistakable. The bird was actually a few hundred yards away, and it did not call back to me, but my iphone speaker is not very loud. I played the common poorwill's call on the iphone as well and it didn't sound like the call I heard. I heard it just at dark in the evening, and then early in the morning the next day
Song or call & method of delivery:	loud and clear call heard and compared to recorded call on iPhone. [Response to a committee inquiry]
Behavior:
Habitat:	The bird was actually calling from up a wooded tributary drainage (Trin-Alcove), away from the Green River. The drainage was pretty brushy, with quite a few large cottonwoods and willows.
Similar species and how were they eliminated:	I played the recorded calls of other nightjars that may be found in the area to compare it to what I had heard, and there was no question it was a whip-poor-will. I also played the whip-poor-will's recording on my phone as it was calling for comparison.
Previous experience with this & similar species:	I'm actually quite familiar with the whip-poor-will's call. I assisted a friend of mine with his masters research in northern Wisconsin which involved locating whip-poor-will's using call playbacks (i.e., I heard it over and over and over).
