"Genus Porphyrula" is a term that you might see in older books, but now it is *genus Porphyrio*. It refers to smaller swamphens with purple coloration. The classification changed because scientists figured out that they actually belong in a different group. The name is a bit outdated. The concept is like using Windows XP when Windows 11 is out now. You can still use it, but it is not the current version. Think of them as the forgotten remix of a popular song.
