behaviour

Birds have their own behaviour. Often, this behaviour seems to mimic human behaviour; birds like to play and ask for attention too.
Birds always need mental stimulation. They must be kept busy, otherwise they will get bored. The consequences of boredom can be feather plucking, but vandalism is also commonly displayed.

With this in mind, you should ask yourself if your bird is really showing bad behaviour, or is it only bored, when it is trying to eat holes in your shoes or trying to break down its cage.

To prevent boredom you can give your bird toys. Birds love all things they can gnaw on, chew, pluck and pull. Colours and sounds are also very interesting for a bird. Try to change the toys regularly, so your bird will not get bored with them. You can reuse a toy every few weeks. Your bird will enjoy it as much as the first time.
Sticks are also a lot of fun for your bird to pick and drag around. Willow sticks are easy to get and they are a pleasure for your bird. Gnawing sticks also keeps the beak in good condition.
