This Manzanita Forked Perch 12"(30cm) - Medium - Hardwood Parrot Perch is particularly strong and resists most bird's chewing attempts indefinitely.
The natural shapes help to exercise your bird's feet and prevent sores.
Although Manzanita can split when drying like any wood, this isn't a fault, merely an indicator of the hardness, your Parrot certainly won't mind. You can wedge rewards in any cracks for your bird to find, they'll love spending time retrieving them.
Be sure to provide plenty of other material for your bird to chew though.
It has a bolt at one end, so you can securely and quickly attach it to your Parrot's cage or play gym stand.
