Frays can be swallowed.
Traps injure feet and beaks.
Unknown hardware is risky.
Remove early.
Huts and cavities can trigger trouble.
Mirrors can change behavior.
Remove toys that fray, trap, chip, rust, splinter badly, expose wire, or make the bird obsessive or territorial.
Frayed cotton, loose threads, and rope loops can catch toes or be swallowed. Rope toys need strict inspection or avoidance.
Avoid unknown metals, cheap clips, sharp chains, split rings that catch toes, and parts that rust or bend.
Happy huts, cloth tents, mirrors, and dark cavities can trigger hormones, guarding, or chewing hazards in many birds.
If you cannot inspect it, clean it, or explain why each material is safe, do not put it in the cage.
Not always, but they need close inspection and are risky for birds that chew fibers.
They are a poor default because some birds court, guard, or obsess over them.
Some hard plastics may be okay for some birds, but cracking, swallowing, and sharp edges are concerns.
Cheap bells can trap beaks or expose unsafe metal. Use only sturdy bird-safe designs.
Use these after the care plan is clear. Match size and materials to the bird you actually keep.
