Why does your cockatiel hump his perch?

It is possible that the claws may be too long and need to be clipped. Special clippers for birds can be purchased from most pet stores, however care must be taken not to cut through the quick of the nail.

Alternatively, vets offer to clip nails of different animals safely for a small fee.

Ways to avoid nails growing to long can be to provide at least one branch with a birdsafe sandpaper cover (also found at most pet stores) which can help file down the nails on a daily basis without causing the bird any distress.

I don't suggest covering every branch, however, as it can cause some discomfort to the soles of their feet.
