They feed on the fish they catch with their beaks in ocean waters. Can you imagine the inconvenience of having to go flying in search of fresh water to drink? So it is. Seabirds are naturally prepared to drink salt water. That's because they have the salt gland!
The kidneys of seabirds are already working trying to eliminate the excess they ingest, but it doesn't do the job. It is the salt gland, located in the heads of these animals, that does the hardest work. This gland removes the salt through the mucosa, through small channels, and eliminates it through the nostril in the form of a secretion that accumulates in the tip of the bird's beak. Researchers have already analyzed and identified that this substance has so much salt that it surpasses the salinity of the sea. As it accumulates in the beak, it retains excess salt, balancing the amount of this substance in the birds' bodies and preventing them from becoming dehydrated.
Seabirds, as the name implies, live exclusively in the seas, oceans and coastal areas around the world. Their bodies are adapted for life in these environments in different ways. The salt gland is one of these adaptations, but we can recall others. In penguins, for example, the wings can assume the function of fins, much like that of other marine creatures, such as whales and dolphins. Seagulls and albatrosses, on the other hand, have flipper-shaped feet, which allow these animals to swim like ducks, of course! In addition to swimming well, these birds can travel short distances or even walk in different terrain.
