I don't know how old Your bird is but it still shouldn't be A problem to 
otty
train. All birds go at regular intervals. Whatch and time the bird for  A 
couple of days first. then pick one spot that the bird is to use for that 
purpose. when it comes close to that time take the bird to that spot and use 
whatever comand You wish for that purpose, (I tell mine to take A dump).
Leave the bird there untill it does It's thing then praise the bird and 
continue playing. In two weeks or less the bird will realise what You want it 
to do and will go to that spot or tell You that it is ready to be taken to 
that spot. Most people do not realize that most pet birds have the learning 
ability of A three year old child or better and this is one of the most easy 
things to teach. I have taught three bird this now and My present Pet will 
tell Me that even when it is on top of It's cage or in the car.
