An Ashinga catching its dinner in the lake near down town Celebration

He has a strange appearance in the water, as he often only shows his head. Out of the water he has to stand around shivering to dry his feathers out as, apparently, he is not a real water bird. I assume the shivering is to shake the water off, not because he's cold.  For all that, he makes a compelling image when he pops his head out of the water.
