A movie about pirates seems almost incomplete without a parrot that talks too much. Parrots can mimic nearly any sound they hear, making them fun pets. However, do they actually understand the words they speak? Let’s find out.
Why do parrots mimic?
Parrots are highly social creatures, and their ability to mimic sounds, including human speech, likely serves an essential social function in the wild. In the wild, parrots often communicate with each other through various vocalizations, and mimicry can be a part of their natural repertoire. It may be used to bond with other parrots, convey alarm signals, or even deceive potential threats.
However, when you bring a parrot home, it is taken away from its natural environment. Just as we feel homesick, parrots miss the hubbub of the busy forests and the stimulation. To compensate for this lack of social interaction, parrots mimic human voices and calls. Sometimes, you may find a parrot mimics the sirens of an ambulance or car horns, too.
A unique neurological discovery also shows why parrots are such excellent mimics. Erik Jarvis is a neuroscientist at Duke University working on vocal learning. His discovery shows birds with verbal learning abilities have a “song system” in their brains. In parrots, though, this song system has an inner “core” common to all birds that can sing, and an outer “shell” that gifts parrots the ability to mimic.
Do parrots understand what they say?
One key aspect is that while parrots can mimic human speech, they do not communicate through their mimicry. When a parrot repeats a phrase, it may not understand the words’ meaning. Instead, they may associate specific sounds with particular actions, reactions, or situations. For example, if a parrot hears the phrase “good bird” after performing a desirable behavior, it might learn to associate that sound with positive feedback.
However, some instances suggest that some parrots do understand the meaning of certain words and phrases, at least to some extent. For example, there have been documented cases of parrots using words appropriately in context. A famous African grey parrot, Alex, studied by Dr. Irene Pepperberg, demonstrated an impressive ability to understand and use words. Alex could label objects, describe their colors, and even grasp basic numerical concepts.
With innovative training, parrots might learn some words and numbers and even understand how to use them. Broadly, parrots mimic human words and language without attempting to understand the context. As we uncover more truths about parrots, we can enjoy the parrot speech as much as possible.
