I have been a nature photographer for 20 years. I have photographed thousands of Great Blue Herons and have never seen this kind of behavior from any bird like this. This bird displayed like this for about 20 minutes and made a sound like a baby crying. It saw me and went to a normal folding of the wings and flew off.

*I've known this for a while ands this is why mankind as he is invested here on Earth, has to make contact with aliens life forms, like him or unlike him and get off of Earth, immediately.
This is the very same posture that some of the leather covered flying reptiles had used.
We're in real trouble if we stay here, I'm not sh*tting you!
