Gee, why don't someone catch it and look up the band number with USFWS or have a vet check for a mirco chip.. Don't look like its been loose to long. I would also check with NAPA to see if anyone on there may have lost it.
Looking at those jesses it looks like it has been free for some time. Hope some one catches it. Did you notice that the jesses were mew jesses and not field jesses. Really hope it does not get tangled in a tree or some other brush.
