[Note Guidelines] Photographer's Note
Ever wonder how a seagull can drink so much salt water and not become dehydrated? The answer is two glands in the bird's head which extract the salt from the blood and excrete it with water which becomes twice as salty as seawater. Tubules collect this and empty it into the nasal cavity, from which it is then eliminated in the form of drops, as shown here in the at the end of the gull's beak.
