Are seagulls able to drink salt water to stay hydrated? Do they have an internal system to filter salt water?

Seagulls and other marine birds have a mechanism called extrarenalosmoregulation. IN other words its a more efficient way of removing salt from the seawater they drink. It is then excreted from salt glands above their eyes.
