How to keep a macaw occupied
Give your parrot manipulative toys.
Parrots can stay occupied by playing with toys that mentally and physically stimulate them. Manipulative toys allow the parrot to move pieces or interact with the toy, which often requires the parrot to think.
Ladders and ropes can provide physical stimulation, while puzzle toys can provide mental stimulation. Some manipulative toys allow parrots to untie knots or disassemble the toys.
