Jan,
I'm so very, very sorry that you are having to go through this. I've played out a similar scenario so many times in my own mind when the FL bird thefts were so numerous in the late 1990s and I've tried to act on what I considered my "weak" points.

One of the things I've done is tint the windows in the front of the house. I can see out but you can't see in unless it's dark outside and lights are on in those rooms. I live in a development/sub-division so my street is not high volume. After dark, traffic is at a minimum. I have motion security lights all around the outside of the house, and those seem to have been a deterrent. Not only do they help me, my neighbors kind of like the idea, as well.

When I built my new bird room, question came up as to which side I wanted the side of the door lock that accepts the key on. I have it set up so that I can lock the bird room on the garage side rather than on the bird room side. Once that door is locked, you either need the key to gain access or you have to break down the door. The door leading to the outside is steel and I've installed a Schlage lock and deadbolt. Needless to say, getting into that room is not easy, although it could be done.

My prayers will continue for the safe return of Bailey and Mika. If they are still in the Phoenix area, posting reward for their safe return, no questions asked, might or might not produce something. A lady in my area lost her African Grey and it took almost a month of posting on the "Lost/Found" area of Craig's List to get her bird back. An honest family read the message and did the right thing. Her bird was less than a mile away.....
