Answer
Some birds--particularly marine birds--use external mechanisms to excrete salt that they take in from food and seawater. Birds utilize salt glands, which are located above each eye. These glands excrete a highly concentrated solution of sodium chloride, which is more than double the concentration of seawater. The salt solution then runs out of the internal or external nostrils, ridding the animal of this excess salt.
