Misting your cockatiels is great for their feather condition and mental health.

First, find a pump-spray bottle that has not been used for any chemical mixtures of any kind. Purchase a new one if possible so you are certain that your birds will not be exposed to anything other than water. Fill the spray bottle with warm (not hot) water. Remember, the disbursement of the spray will cool the water considerably, so by the time it reaches your bird, it should be room-temperature. Make sure you use fresh water each time you spray, as bacteria can build up in a water bottle. Some people add just a drop of glycerin to the water, which will break down the oil buildup on the bird's feathers, but this isn't necessary.

To avoid chilling your bird, make sure he is not in a draft, and do not spray a bird in the evening. Mornings and early afternoons are best for bathing your cockatiel, because it leaves enough time for them to dry thoroughly before the cool of evening.

If you worry about getting water on the walls, woodwork, etc. around your cockatiel's cage, simply drape a towel or sheet over the cage and leave one side exposed... then spray away!

Some cockatiels don't enjoy bathing this way right away, but all will eventually lift their wings and roll their heads down, joyfully capturing all the spray under their feathers.
