Heard initially @1812 and again @1904 on 11/07/21.
Best snippet attached as WAV.
BirdNET came up blank.
Visually compared to Barn [#3 of 8] & GHOW [Begging calls] examples that were sourced from eBird, recorded on my phone and then analyzed on BirdNET. GHOW seems closest. Also two adult GHOWs were heard calling back and forth at a distance for the latter occurrence.
I haven't heard a fox calling in some time to be able to recall its characteristics. That's a possibility, but the sound seemed to be sourced both near and then far too rapidly for a ground source. Loudness also seemed off for a fox/coyote unless it was actually in the yard.
