OK, don't laugh, but at first glance, I thought you had captured a gull flying upside down. Yeah, I know they can't do thank, but still..............:-)
That's what you say now Marijke...................maybe your thinking what a dumb cluck that old Kentucky boy is.....and you would be close to correct.
I didn't laugh Larry (I might have smiled though!) - last week I was watching ravens playing and they did fly upside down - just because they could! They also 'pretended' to fall out of the sky and then flew up again - lovely to watch!
