Is he trying to mate?

[TopalBird]

Ok, this may sound crazy but this old feller (Topal) has been acting a little strange with his cup. He has been playing with a Mc Donalds Cup in his cage, and my husband thinks he may be trying to mate with the cup. He says that he has been purring and putting a leg up on the cup. LOL!!! He loves this cup..It has really been keeping him occupied latley, and also he lets me hold it while he tries to tear it to pieces. I don't even know if he is really a male or not, but this new behavior is very interesting to me.

They will act as you describe when they really like an object. It is not sexual behaviour though. It's funny to watch them become so excited with an object such as that. There will be others. :-)
