Cage birds sometimes develop annoying habits as a result of excess
energy and playfulness. They may get in the habit of tugging at the
paper on the cage floor; or if they have a band on their leg, they will
sometimes pick at it until their leg becomes very sore. Ridding a bird
of such annoying or harmful habits will be a good test of your
ingenuity. In the case of a leg band, the easiest thing to do is to
remove the band. A change in the location of the cage might help.
Sometimes a new cage of different shape or color will turn the trick.
Some owners allow their birds the freedom of a whole room and this
usually is beneficial--providing windows and doors are kept shut.
