In the past, it was thought that birds had a poorly developed sense of taste. Taste buds lie at the base of the tongue, in most species of birds. Some birds have taste buds on the inside of the tip of the lower and upper bills and there are several sites on the roof of the oropharynx, near the choana. In parrots, the taste buds are on the roof of the oropharynx on either side of the choana, and on the floor of the oropharynx at the front end of the laryngeal mound. Humans have around 9,000 taste buds where parrots have only 300-400. Birds do have a sense of taste, and do show definite taste preferences, as we all know!
