This one was interesting @sambiology @brentano @charley @lulubelle This one is kind of baffling me. It just appeared out in front of me and my mother when I was at the lake chasing dragonflies and things. It was about King bird sized and was black and had white under his chin and all the way down it's breast and belly. The rest was a slate black color. It was very interesting but it is baffling my brain.
