I'd go along with Pacific Chorus Frogs. Or as I tend to know them
Pacific Treefrogs.
Not seeing them is more or less the stamp of the entire chorus frog
group. The Uplands Chorus Frog, one we have that happens to be calling
right now, I usually spot as a short white line that does not seem to
belong. Only after watching the line for a little does it turn into a
frog with a white line on his lip. Kind of like the Disney cheshire cat
in Alice. It's a very small frog.
Chorus frogs are small, usually choose a nook in the grass that has good
acoustics and affords some protection from prying eyes. They usually run
under the vegetation rather than hop out where they would be seen. Last
time I was out west, in the fall, I spent two weeks at my folk's place
trying to spot the Pacific Treefrog that was in the thick vine by the
front door at eye level and would occasionally give one of their
location calls. I never found him, even though I knew his location
within a few inches. Would have been a lot easier during breeding
season. You can zero in on them by their calls if you take the time.

The other thing you will discover is that hydrophones pick up nearby
well pumps very well.
