Sea birds have salt glands to help them excrete excess salt from the seawater they ingest while feeding. These specialized glands, located near their eyes, filter out salt from their bloodstream, allowing the birds to maintain proper hydration and electrolyte balance. This adaptation enables them to thrive in marine environments where freshwater is scarce. By expelling concentrated salt solutions, they can drink seawater without suffering from dehydration.
At the corner of their eyes.
All sea turtles drink only seawater all of their lives. They have special glands behind each eye, called "salt glands" that they use to get rid of all the salt from the seawater.
Marine birds and reptiles have glands that secrete excess salt from their systems.

Some animals, like marine mammals such as seals and sea turtles, have the ability to drink salt water and excrete excess salt through specialized glands.
Very simply, they are adapted to work in salt water (and for the birds, in air too).
the sea turtle can actually drink salt water. there are salt glands in the back of their head that removes salt. when a sea turtle comes on land to lay it's eggs, the salt that was removed from the water will come out as tears that will keep their eyes from getting dry.
Flamingos have specialized glands located above their eyes that help them excrete excess salt from their bodies. When they consume saltwater while feeding, these glands filter out the salt and transport it to their nostrils. The excess salt is then expelled through their nostrils, allowing them to maintain a proper balance of electrolytes and hydration. This adaptation enables flamingos to thrive in salty environments where other birds may struggle.
Sweat glands excrete sweat ( which is mostly salt and water).
Yes, birds do have salivary glands. However, their salivary glands are relatively small compared to mammals and produce a less viscous saliva. Additionally, birds primarily moisten their food with mucus secreted by the walls of their esophagus, rather than relying heavily on saliva for digestion.
The salt glands excrete excess salts and water from the body. The urinary tract is also used for this purpose through the kidney.
