Recorded this call in Cuyamaca Rancho State Park, California. About an hour east of downtown San Diego. Elevation ~2000 ft, beautiful park in the Cleveland National Forest. I was able to see this bird briefly with my binoculars, looked to be at least crow-sized if not larger and I could see a pale underside, sort of a tan color, but couldn't see much else. Got the call on video but haven't found any good matches. I've attached a video, but it doesn't show the bird, so I also attached an audio-only version. Sorry for all the background noise!
