What bird makes this sound?

I live in the Southern California desert and I hear this bird all the time in my neighborhood. It goes woooo (pause) Woo-Woo-Woo. That’s it: a long woo followed by three shorter woo’s. Each “woo” start low but then increase in pitch. Please help I know this seems like a weird question but I have been scouring bird sound boards trying to find it because I love the sound so much and I want to know what bird it is. It is taking me forever to listen to these sound boards. I am thinking it is some kind of owl but I haven’t found it yet.
