Here's one approach on how to introduce new toys to parrots:
You have a new toy that you want to hang in the cage, but as soon as your parrot sees it he leans away, obviously scared of it. You can use desensitization to introduce it successfully:
✔️Hold the toy no higher than about chest height where it is visible to your parrot and move far enough away that he or she shows no signs of fear.
✔️Slowly walk toward them, one step at a time, carefully observing their body language.
✔️At the first sign of alarm, stop approaching and take one step backward.
✔️Put the toy somewhere at that distance, at a level below your parrot’s typical perching height, so that they can easily see it.
✔️Every day or so, move the toy a little closer to your parrot. If you ever see a sign of alarm when you do so, put the toy back at the last distance and allow your bird to look at it a little longer at that proximity.
✔️When you’ve been able to move the toy right next to the cage, hang it on the outside of the cage down low.
✔️Move it up to the middle of the cage, still on the outside.
✔️Move it up to the height at which you would like to eventually have the toy.
✔️Move the toy inside the cage
👆Monitor all toys and the parrots playing with them to ensure they are not eating any loose strands.
