For over two decades, Professor Toshitaka Suzuki dedicated his life to studying the Japanese tit - a small songbird native to Japan's forests. Through years of careful observation and experiments, he discovered something incredible: these birds use grammar-like rules and combine sounds to form meaning, much like how humans use language.

In this video, we explore how his groundbreaking research challenges what we thought we knew about animal communication, and what it might mean for the way we understand intelligence in the natural world.
