Cockatiels, like all parrots, are vocal creatures by nature. Not all cockatiels are musically “wired”, but most can be taught to whistle, or sing. Like with any tricks you teach a parrot, patience and repetition is required, but you and your parrot will be well rewarded with the results.
Here’s a parrot for Star Wars fans. This cockatiel has mastered the beginning of the Darth Vader Theme song. He started whistling from about 5 months old. Have a look at the video and let us know what you think of this little guy!
