yes. I think Aviraut just has has the Leonada. at least thats all I see on there Facebook page and website. Though I can ask Dr. FranceschThey use it both ways there. I get what you are saying, but they do use them interchangeably. A lot of sites from Spain has them listed by the full name. Some just call them Prat Fowl.
And Leonada is the color. They have white Catalanas also. The Catalana or Prat fowl comes in two colors. I imagine it is like New Hampshire or New Hampshire Red. Everyone knows what everyone is talking about.
