The bird is most likely the Sooty Tern, it can stay above land for 3 to 10 years. However, I don't think a Night Fury is related to their style of always flying. Sure they have excellent stanima, broad wings, secondary wings and tail fins, supremely adapted for flying, but they are also adapted to land, as they can run fast, and sleep and rest on the ground.
