In all seriousness though I did have birds getting their heads taken off.
Like the OPs it was just the head gone and no other disturbances to the body. No blood, feathers, tracks etc.
One morning as the sun was just coming up I went and set on back steps and was drinking a cup of coffee.
Birds weren't really moving around much yet and there was a group of ducks out laying in the yard about 20 feet from me.
Out of the corner of my eye I saw something and looked over in time to see an owl fly by and land on a fence post. It was absolutely silent when it fly by but huge.
As I tried to register what I was seeing I saw it eye the ducks and kinda hop in the air and start to swoop their way.
I'm not sure what my plan was but I was closer to them then it was so I jumped up and ran towards them.
Thinking it would be scared off or maybe throw my coffee at it. Idk but I was gonna stop this attack.
Guess the owl was pretty committed also because about the time I got to them with my arms waving around that SOB slammed into my chest with the force of a mack truck nearly knocking the air outta me.
Guess luckily with the force of impact I didn't feel both talons pearcing into my chest. He was stuck to me like velcro.
Next thing I know he is flapping his wings like crazy trying to take off with me in tow.
I'm not talking about a cute little how many licks does it take to get to the center of a toosie pop owl. I'm talking a huge 6' wingspan out for blood winged beast from hell.
Next thing I know I can feel my feet almost lifting off the ground.
Feeling like Richard Harris in a man called horse I'm dangling from the massive talons ripped into my chest.
About now I'm realizing apparently an owl must have a lot to live because he was taken this whole indecent pretty d*mn serious.
Figuring I needed to end this now before he carried me off into the woods I decide a good ol *ss whooping was in order. I pulled a Rocky vs the Russian and started hammering him in the rib cage with blow after blow.
To my surprise he was unfazed. Then our eyes met. They were huge like saucers and I could see down his throat as he keeps screeching. Who, who, who who's your daddy.
I was pissed now and grabbed him by the head to give him a good neck snapping.
Not the easiest thing to do to an owl.
I twisted and twisted and his head just went around and around and around and around. He finally broke loose and I knew I was in trouble as I saw his head spin back around and around. It was like out of poltergeist.
With me now running out of options I was glad to hear a familiar voice behind me.
I say, I say boy you're going about this all wrong. Let me let me cut in on this dance.
Next thing I hear is a huge "brooong" as my old friend foghorn cracks him upside the skull with a cast iron frying pan.
The owl falls to the ground and in an instant pops back up and flies away.
Luckly my wounds weren't too serious so I taped some asprians to them and spent the rest of the morning with an old friend talking about how to handle stupid hounds, chicken hawks and fickle hens.
Now before you start saying this story sounds a bit unbelievable I can assure you I found it unbelievable myself but owls are incredibly silent when they fly.
