This just in from MMM, who is having problems with velcro birdy not staying in the birdy safe area.

Bird 10, people 11. Nailing one side of the curtain to the door frame didn't work. Adding velcro to the other side of the door frame didn't work. As fast as we we put up an obstacle, she breached it. Now---------we'll see. So far, so good. Sad bird. (expensive sad bird)
