This guy was ‘struttin his stuff’. And that’s hard for an Anhinga. Those huge, flat, webbed feet don’t hang on branches very well. In fact I’ve seen them fall out of trees.
The Anhinga dance is different than others in the rookery. He hangs on, sits up, and spins his wings…backwards.
It’s a bouncing back stroke.
