Question: Do birds have a sense of taste?
Answer: Yes, and insect-eating birds have a more developed sense of taste than do seed-eating birds. This is because many insects are poisonous and by having a better developed sense of taste, birds can avoid eating insects that might harm them.
Because of this, some insects have evolved to taste bad for their own protection, while other insects have evolved to look like bad-tasting insects (Batesian mimicry) for their protection.
