Good call on this one Michael and Andy. I completely agree, having now reviewed the samples provided at Steve Kelling's flight call website and some other resources (thanks for pointing that out again!). I've only heard Virginia Rail overhead at night producing their "kid-dick" calls. I had noticed that the frequency was high, but it seemed within the realm of possibility for the similar Red-headed Woodpecker NFC, but, I'll have to go with Virginia Rail on this one, too.
Upon comparing the two in Raven, it seems that RHWO does indeed have more harmonics, is lower in frequency, and the RHWO call has connected modulation, giving it a thicker "churrr"-like quality, while Virginia Rail "kicker" call seems to have very few harmonics (none, except perhaps at the onset?), is slightly higher in frequency, and has disconnected modulation, giving it a dryer "reedy"-like quality. Thanks for posting the sound, Rob. This was a good learning experience for me. I hope to record more this springtime (Etna, NY), so perhaps will encounter my own Virginia Rail call in the coming days/weeks. Good night listening!

I remember emailing the call to Steve and he felt confident it was good match for last part of "kicker" call of VA Rail.

Got another one last night. Would love input on this one. It sort of looks like SWTH spectograms, but doesn't sound like it at all. Ends with a nice burriness.
