A researcher once hatched four cockatiel chicks and whistled a popular song, the Mickey Mouse Club March, near them fewer than five times a day. Three of the birds began to whistle the tune on their own by about 100 days old. They started by singing fragments and then joined them into the whole song. These little parrots are incredibly talented! So why do cockatiels whistle? Is it music, speech or a shout for help? Let's start with a quick decoder, then you will read more about it.

The Whistle Decoder

Follow this as a handy reference. Always read the whistle in conjunction with your bird's body and the situation.

  1. A loud repeated call when you leave the room – "Where are you? Come back." A contact call to a missing flock mate.
  2. A long, happy song to a mirror or shiny object – Usually a male showing off. He is singing to the "bird" that he sees.
  3. A copied tune, ringtone or wolf whistle – Your bird is copying a sound from home and is attempting to connect with you.
  4. Whistling alone to a toy – May be boredom. Your bird is creating its own amusement!
  5. Happy whistles when you come home – Complete joy. You're home and the flock is full.
  6. A whistle-scream with a raised crest – Alarm or fear. Look for something scary nearby.

Whistling Is Flock Talk

Wild cockatiels live in social groups, or flocks, in Australia's dry open country. In the wild, calls are used to hold the group together and alert them to danger. A cockatiel at home still thinks this way. Your family is its flock and you are one of them.

This is why many cockatiels will start shouting for you when you are out of view. Bird experts call this a contact call. The bird is looking to see where you are. A simple reply from the next room will often bring it back into a state of calm.

Cockatiels are also most vocal at sunrise and sunset, similar to other types of parrots. However, a contented bird can start singing anytime!

Why Males Whistle More

Male cockatiels are the famous singers. They tend to sing long whistle songs to their favorite person, a toy or their own reflection. Some can become so excited about a mirror or a shiny vase that they sing to it for long periods.

Whistling is also possible for the females. They just tend to do it less. Males are also more likely to learn words, although cockatiels generally prefer whistling over talking.

Copying Is How They Bond

Cockatiels are a naturally mimicking species. They learn whistles that they hear frequently, such as your whistle, a phone, the TV or a radio. Many acquire wolf whistles, theme songs and doorbell noises.

This copying is not done at random. Birds learn the sounds of their flock and fit in with it. If your cockatiel mimics your whistle, take it as a sign that it is "speaking your language" and keeping close to you. The birds in the above study often whistled the song right after being left alone. The researcher suggested they might use it to attract human attention.

When a Whistle Means Something Is Off

The majority of whistling is a positive sign. However, there are a few patterns which should be examined more closely:

  • Endless calling all day could be a sign of loneliness. Cockatiels are social creatures and require time with you each day.
  • Whistling only to a toy, for hours, may mean boredom. Introduce new toys, especially ones it can chew and shred.
  • Screams with a raised crest or hissing point to fear or stress, not happiness. Our guide on why cockatiels hiss explains that warning signal.
  • A bird that suddenly becomes silent may be sick. If a cockatiel that normally whistles stops whistling, it should be seen by an avian veterinarian.

Can You Teach a Cockatiel to Whistle?

Yes, and it's a pretty nice way to bond. Choose one short tune and whistle it a couple of times throughout the day to your bird. Use the same tune each time. Reward your bird for any attempt. Some owners also play recorded whistle tracks. Be patient, it may take weeks. Many cockatiels also learn to whistle back on cue. Pair whistling with other cues your bird uses, such as the head bobbing you see in budgies, and you will slowly be able to pick up its entire "vocabulary".

Before You Go

Cockatiels whistle to communicate with their flock, to show off, to copy the sounds they enjoy, and sometimes out of boredom. Know the code, look for the crest and whistle back. To your cockatiel, that reply means you are part of the family.
