A barn owl is not a bird, with or without such 'horns'

ok it's been far too long so it's time for the big birdreveal;
Birds are organisms which possess distinct visual bilateral symmetry
ie; species with asymmetrical organs didn't count, it had to be something you can see somewhat
Asymmetry like that is pretty rare in Bilateria, since all Bilateria originally were symmetrical, with asymmetry being an evolved trait for various reasons (like snail shells or owl ears)

Birds are characterized by their trait of when you show them to either my cat or my dog (separated since 2002), they will get upset.
