It is important to provide your bird with a variety of toys to prevent boredom and behavioural issues such as shrieking, yelling, feather plucking and aggression.
Some examples of toys and activities that will prevent boredom:
talking to your bird
new sounds and sights
Remember to rotate and change the toys often!
