I am staying at a Airbnb house in the Santa Susana Mountains area of N/W Los Angeles County.   I made this video late at night to capture the sound of something making a very loud noise about every 10 seconds.   It is on the roof of a vacant 2-story house next door, or the surrounding trees which are in the 30ft tall range.  I have heard loud owls in this same area before (Unknown which type, but sounds like "Hooooooo.  Hoo hoo."  Typical owl sound).   I'm wondering if this is a baby owl?  In the background, you can hear another bird (Owl?) screeching.   Maybe answering?    The noise can go on for hours, but it does move around within a 50yd radius of the house.  In person, it is very loud and almost sounds like some sort of pressure or blow-off valve.  One night it was on the roof of the house I am staying in, by the chimney.  The sound of it walking around leads me to believe that it is quite heavy, much more than a crow.

I have listened to various owl-sound videos on YouTube, but could not find a match.    Thanks in advance!

That’s a very human sound.

This would be my guess.

Squatch.

Squatch or human weirdo, once you’re lured out to “look around”, it’s going to buttrape you. Whatever it is, those are buttrapist sounds for sure.

Young owl, just as a guess.

you have roof deer
