This is Leech, who is an extremely friendly bird. So friendly, he didn't want me to leave and, on receiving my keys as a toy to play with, promptly found the most important one on the ring -- the car key -- and snapped it in half with his beak.
This is Nuggy, caught doing a very strange dance while being given a bath. With even more powerful jaws than Leech, it is no wonder I run like hell from this bird. He's punctured my shoes several times while trying to get to my toes and has crushed rings to the point where they begin to cut off circulation and cannot be removed without the help of the garage vice. Fingers could easily be taken off, even if done not in anger.
Nope, I don't get the whole bird-ownership thing.
