Patrick used to make the prettiest sounds trying to woo Tika, and when she would respond to him he'd go to her cage and she'd bite his toes. He kept trying though!
The red-belly owner said to put a piece of acrylic on the top of the cage, but even Robert knew that was a silly idea: most often the birds land on the sides of the cage, not the top, and they climb all over the outsides.
I just hope we can find a budgie for adoption that is remarkably tame and something along the lines of cuddly. Not likely but I can dream =P
There was also this small pink bird I saw one time at a parrot rescue, looked like the budgies it was housed with but it was called something different and they said it was from South America. I'm sure I wouldn't find one in a rescue though.
