Manzanita wood is known for being one of the hardest woods that is safe for birds.
These perches are perfect for your birds that love to chew and play with the perches in their cage.
Please note: While these perches are VERY hard, birds are also very clever, and may chip or wear down the wood over time. That means the perch is doing its job!
The MEDIUM size is appropariate for any MEDIUM sized birds, from Small Cockatoos, African Greys, Amazons, and any similarly sized birds.
