The glaucous-winged gull eats mollusks that have hard outer shells by dropping them onto coastal rocks from the air to break them open.
The glaucous-winged gull eats mollusks that have hard outer shells by dropping them onto coastal rocks from the air to break them open. How does the gull know to do this to get to the food inside the shell? The Creator either gave the gulls the ability to learn this behavior, or it was programmed into the gull from the beginning.
