Laughing Gull
Why is a river rich?
It has banks on both sides.
Interesting Fact: The adult Laughing Gull removes the eggshells from the nest after the eggs hatch. If the shells are not removed, a piece can become lodged on top of the slightly smaller unhatched third egg and prevent it from hatching.
