Colorful, extremely fast, and entertaining. Almost all the photographs are throw away’s. But they are fun.
In the image above (enlarge to view) you can see the odd shaped bill, and the fish being chased.
The top beak is shorter than the bottom. This bird dips his beak along the waters surface and slams it shut if it touches a fish.
They fly at a great speed to get momentum right before they drag their bill through the surface.
