The good news is they keep coming back, one way or another. From the Evening Star (UK):
TO lose one parrot and get it back may be considered lucky - but to do it twice is truly amazing.But lucky Lucy the parrot is back home safe and well today after a frosty night out on the tiles - four months after her mate escaped and enjoyed ten days of freedom.
The African grey went missing from her Felixstowe home on Christmas Day.
Owners Linda and David Whitaker cannot make out if their pets are egging each other on in their bid to see the outside world or not, but they know they are incredibly lucky to have lost two and got them both back.
Lady Bracknell: ...Now to minor matters. Are your parents living?
Jack: I have lost both my parents.
Lady Bracknell: Both? ... That seems like carelessness...
