During one of our visits to Viera Wetlands, we saw this Anhinga playing with a piece of pipe. Anhingas hunt by swimming under water and spearing fish with their sharp bills. They then have to manipulate their prey in order to eat it, which usually involves tossing the fish into the air from the perpendicular and catching it as it falls parallel into its throat. These photos I found on Flickr show the toss and catch process. We were both enthralled and amused watching this Anhinga’s antics as it practiced its prey-flipping skills.
