Not going to make a big deal about it, but you’ve got some pretty similar sounds in the Ukraine and in Canada at about the same time – within the last couple of weeks.

And you’ve got the same thing in Belarus at the same time.

And this was Tallahassee, Florida back in March. Not exactly the same sound but similar.

I have no explanation for this at all. It’s strange. If somebody has a clue, feel free to post one in the comments.
