Do you believe in magic?
Birds are magic. if you believe in birds you must believe in magic. Birds can fly, not unlike magic carpets or spells.
Birds also lay eggs. Eggs are magical vessels for all the ingredients that make a new bird. Coincidence? No, magic.
Eggs are mixing bowls, but with a magical closed lid that only opens when the magical baby bird has been cooking for long enough and is ready to be released.
Birds decide not to talk human. they could, but they don’t. they decide to communicate through song and mimicry and whistling. that’s magic.
