Do Parrots Understand What They Say?

Most parrots are experts at mimicry (copying sounds). In the wild, they copy the calls of their flock members to share information and stay together. When they live with humans, they treat their owners as their flock. They copy human speech, telephone ringtones, or doorbells to fit in. For many birds, this is simply repeating noises they hear often. If a parrot says “Hello” when someone enters a room, they are often reacting to the action of the door opening rather than intentionally greeting the person.

Evidence of Understanding

Scientists have discovered that some parrots can learn the actual meaning behind words. The most famous evidence came from an African Grey parrot named Alex. He worked with a scientist named Dr. Irene Pepperberg for thirty years. Alex did not just copy sounds. He learned to identify over 50 different objects, seven colors, and five shapes.

When shown a tray of mixed items and asked, “What color is corn?”, Alex could answer “Yellow.” He could count objects up to six and understood complex ideas like “same” and “different.” If he wanted a specific food, he would ask for it by name. If he was given the wrong item, he would say “No” and ask again. This proved that some birds can use human words to express their own thoughts.

Brain Power

Parrot brains are quite different from human brains, but they are very powerful. While their brains are small, the neurons (brain cells) are packed very tightly together in the forebrain. This is the area used for thinking and learning. This dense brain structure allows them to solve puzzles and learn language skills similar to a human toddler. While not every pet parrot understands what it is saying, intelligent species like African Greys, Cockatoos, and Macaws are capable of connecting words to real objects and actions.
