Is it true that the ostrich's brain is the size of its ears?

Yes, the ostrich’s brain is about as big as its ears. The ostrich has a very large brain in relation to its body size. The average human brain weighs around 3 pounds and an ostrich's brain can weigh up to 8 pounds. The ostrich's brain is also relatively small compared to other birds. For example, the chicken has a larger brain than the ostrich.
