Found a mate maybe?

Don't know but was a very high pitch not at all like the sort of noises I have heard a koala make .
Somewhat like the sound of a Tasmanian Devil (fighting) except that we were in the Otway (Victoria)

The bone chilling sobs of La Llorona.

I was hiking around off trail in my local state park. It was getting dark, I was just trying to get back home. I was passing through a section of the woods where there must have been 100 turkeys all going crazy and gobbling. It was very disturbing. Like a giant turkey music festival. Then, out of nowhere, I hear a person let out a bloodthirsty yell and the sounds of turkeys fleeing. Some weirdo was out there in the dark stalking turkeys like some kind of feral tarzan man. I think he heard me walking after that and hid from me.

Hi Franco

Otways eh?
Probably a Geelong supporter after a bad result.

Around sunset on a dayhike in Briones, a regional park that while surrounded by urban development, is known to contain cougars, bobcats, coyotes, etc., I heard something I've not been able to identify by listening to various audio clips. By far the closest match is Robert Plant's screech at the beginning of Immigrant Song. (abbreviated, about two seconds of arraaaaaaaaaahh!, repeated)

One of my favorite sounds is that of the loon. I never heard one until I got to go camping in the BWCA years ago. You guys up north probably don't think any of it because you hear it all the time- but I really thought it was such a cool sound.
