Question: do birds have taste buds?
Answer: Taste varies, too, but in general, taste is less well-developed in birds than it is in humans. A parrot has 300 to 400 taste buds, while humans have 9,000. Most birds can perceive sweet, sour, and bitter tastes. A bird that lives on nectar and fruit will prefer sweet tastes, but sweets don't appeal to grain-eaters.
