One of their most striking features of the Black Skimmer are it’s red-and-black bill and as you can see here, they’ve got a lower mandible that juts out farther than does the upper. When feeding, the Skimmer flies low over water with its beak open and lower mandible partially submerged. When the lower part of the bill touches prey, such as a small fish, the bill’s upper mandible snaps down like a mousetrap, securing the bird’s meal.
