One thing I discovered about having a lot of birds and an outside aviary, was exotic birds that have escaped from their owners, find you.

Several years ago I was visiting a breeder when something climbed up the outside of my pant leg. It was a blue headed pionus, named Maximilion. Maggie as I called him had been sold twice and returned. No one could keep Maggie in a cage. He was only two years old and cage containment was easily solved for me. I took the bottom out of Maggie's cage so he could come and go as he wanted. Leaving cage doors open added to the poop on the floor and uninvited guests, which Maggie hated. No, not the poop on the floor, he really didn't care about that.
