Why can parrots talk & dogs can , considering parrots have smaller brains?
As many others have pointed out, brain size is irrelevant. Parrots are the 5th smartest animal in the world. Dogs are 7th. Parrots have both the vocal chords and the brain capacity to mimic various sounds. They can do phones, car alarms and voices. Their ability to communicate through speech is very limited as they usually don’t understand what they are saying.In the wild it’s a defense mechanism. In captivity they use it to get love and attention. Great apes are the smartest animal and they are completely incapable of speech.
Parrots don’t just mimic sounds, some parrots can actually converse intelligently with humans. I read an article on BBC a while ago about an American woman who studies birds and has an African Grey that know’s colours, shapes and textures and can tell her what he wants and what he likes/dislikes. My Quaker Parrot can talk to a certain extent especially when it’s time for the kids to go to bed he goes up with them, kisses them and says night night, lights out. It’s so funny and he only does this at night time if he goes up during the day or in a morning he doesn’t do this.
