This scene was quieter than I would have expected but the dancing and flashing of the Brown Thrasher (Toxostoma rufum) certainly caught my attention. The coiled up object near the center of the frame is a snake.
Based on the brief glimpse I caught of it quickly slithering away later, I am guessing the bird was harassing a Black Racer (Coluber constrictor priapus).
In case anyone is keeping score: Thrasher 1, Racer 0. And yes, I know, I need to work on my videography skills!
