One of the smallest birds on the list is the budgie. Budgies (short for budgerigar) are small but mighty thinkers. They are some of the easiest parrots to adopt, making them a great option for beginning bird owners looking to explore training. Budgies are great performers, capable of a wide range of tricks. They can also be trained to talk, so if you’re looking for a humorous vocalist, they can be a great option.

7. Indian Ringneck Parakeet

While Indian ringneck parakeets are related to budgies, they’re a bit larger. These birds are generally around 16 inches long. Only male ringneck parakeets develop the rose-colored ring around their neck.


Related to the budgie is the Indian ringneck parakeet. These parakeets, also called rose-ringed parakeets, are known for the unique coloring around their necks. Indian ringneck parakeets demand a lot of attention, but they bring incredible smarts to the table. These birds are great vocabulary learners. They don’t mimic the human voice like some species of parrots do, but they can develop extensive vocabularies, making them one of the smartest parrots in the world.

6. Monk Parakeet

Another small bird on the list of smartest birds in the world is the monk parakeet. These bright parakeets are about 11 inches long and live in the wild in South America and the tip of Florida. Monk parakeets are illegal to own in some states, so be sure to check your local laws if you’re looking to adopt one as a pet. Like the other parakeets on this list, monk parakeets in captivity can mimic the sounds of their human flock. As they practice, their vocabularies can grow quite large.

5. Macaw

They can talk, do tricks, and even execute tasks! These birds got their names from the word “eclectic” because of their bold and varied coloration.

3. Cockatoo


Some cockatoos demonstrate exceptional problem-solving skills. Cockatoos have been observed picking locks and solving puzzles, so be careful what your bird has access to!


Another smart parrot is the cockatoo. These mid-size parrots reach around 18 inches in length and are wonderful pets. They can learn to talk, though they aren’t as chatty as some of the parrots on this list. However, the birds are still extremely intelligent. Studies have proven that cockatoos are indeed smarter than human toddlers, even if undomesticated!

2. Amazon Parrot
