Folks, I'm impressed. This is indeed a grosbeak, a juvenile black-headed grosbeak. There were two family groups in my yard the day I made this recording, at one point 7 or 8 were making this call simultaneously.
I couldn't find the call on my Sibley app or on other on-line guides either. I checked xeno-canto there were ~6 or 7 juvenile/fledgling calls of black-headed grosbeaks posted (out of ~180 recordings). Several were described as juvenile begging calls; that seemed like what was going on in my yard. They are still around but the begging calls are diminishing.
