BIrd call that sounds like a human voice

Probably a ghost or a member of the swedish bikini team.  What was it that you thought she said?

Google and listen to the sounds a red fox make. If not that, then what pete said.

In all seriousness, my experiences on the JF with strange sounds have all been directly related to the amount of alcohol I have consumed.

Here's the scale"

1-6 beers- some sort of owl, frog, bird

6-12 beers- a deer, no way it has to be a raccoon, maybe not.... what if it is a mountain lion.

12-15 beers- I think I'm hearing dung, eh who knows but I sure love being out in the wild. "Puts stick in fire and gets the end hot" if that son of a b... gets any closer, I'm gonna protect myself and stab it to death with my newly created weapon.

15+ beers- what sound?

Thank you all for the suggestions. I looked into them all but none quite fit. The sound was very musical and absent the screech or rasp of a bobcat or fox. The closest tone and timbre is the great horned owl.
