How do seabirds drink seawater without getting dehydrated?
Quick Answer
Many seabirds have salt glands that remove excess salt from their blood, letting them drink seawater or eat salty prey. The concentrated salt solution is then expelled through the nostrils or beak.
The Full Story
Seabirds such as gulls, albatrosses, and petrels often live far from freshwater sources. To handle salty food and seawater, they have specialized salt glands above the eyes or near the nose. These glands filter out excess salt from the bloodstream and produce a brine-like liquid. The bird then sneezes or drips out the salt, which keeps its body from becoming overloaded with sodium.
