why do people say "bird brain" ? Birds are smart!

It certainly is a common stereotype, probably in part stemming from cartoons and other entertainment. I don't think the size of the brain is the defining factor, however. I remember recently reading that some scientists have discovered that many insects brains are capable of far more than we had ever predicted. For the most part I'm a man of science, but I do believe some people believe in science a little too much, and as a result they perpetuate misinformation from baseless research which spreads across many communities, and in the end many people believe it. I think many scientists refuse to accept that we as humans don't actually know that much about neurology yet, despite our accomplishments.

As you've said, birds are capable of a lot. Many animals are, but we humans allow our arrogance to see other animals as lesser lifeforms in nearly every regard. You only need to watch a few documentaries to see the incredible things those with tiny brains can do. We might have come a long way and have technology on our side, but if we had to survive in harsh conditions, our efforts would be laughable compared to many animals'.



It's a Banana Bird!
