There's a bird here in Brazil, the "quero-quero" ("southern lapwing" or Vanellus chilensis) that sports a couple of 1cm-sized spurs on each wing, used to intimidate rivals or enemies while flying. They nest in grasslands, being very common to be found in soccer camps and sometimes disturbing the trains because they try to protect the nests (for the amusement of those who watch the trains :D)

@@AifDaimon The wyvern/dragon distinction is made up, and not as widespread as you might htink. If you want to look at dragons through the lens of mythology, you quickly find that the concept of "dragon" is more of a handful of distinct narrative roles than a physical description; some dragons are mashups of various specific animals, some are just huge snakes, etc (consider the fact that _every_ culture has a dragon-concept; if they were defined by body type this would not be true). If you want to look at dragons through the lens of modern fantasy pop culture, then there are no fixed rules because that's not how art works.
