Andrew,I looked at some BB Plover calls at Xeno-Canto. None of Xeno-Canto BB Plover calls (measured at top of initial hook) were below about 2.8 Khz.
Looked at BB Plover calls at Cornell Library of Sound too but find Ravenviewer a little frustrating. My mouse pointer does not seem to calibrate with frequency shown on screen so its difficult to accurately assess the calls.
One of calls at Library of Sound (#3027) measures at 2.68 on Ravenviewer. Looks like the error on my screen is about + 0.24 when the upper freq limit is set at 5 Khz. This puts it a little bit closer to frequency of bird you recorded.
I have a possible Wood Duck call, recorded at night last May, I can send if you want.

Thank you Chris for posting the cut-down. Does anyone like Wood Duck? There are ducks in the area flying around pre-dawn and this morning they sounded similar. I listened to Stokes' and there is a single call that sounds similar (i can't seem to load it though to analyze the sonagram). The ML's wood duck collection shows a wide variety of frequency and types of calls for Wood Duck. p.s. Black-bellied Plover was selected which is a good match for quality and sonagram. Stokes' recording is a bit higher frequency than my recording. Does frequency change with distance or echo? ML doesn't have much audio for Black-bellied Plover, but what is does have is a fairly similar.

I've gone all the way through Stokes and Lang CD's and I can't find any matches and it doesn't ring any bells beyond Sora (which it doesn't match). A couple of shorebirds started to vaguely sound similar, but not close. I can send an mp3 (~2 MB) to anyone that wants to listen.
