I've never sold birds on Craigslist, but I have bought and sold trucks. Rules for safe selling: (learned from the guy I bought my Ford from)
1. Never put your address
2. Never put your landline number, too easily traced to your address. Test this yourself. Go to Google and put in your landline number. Your address will probably display in about 15 seconds.
3. when I show a truck I am selling, I never show it at my house. I put it down at my mechanic's shop and meet my potential Craigslist buyer there. Public place, witnesses I trust, and the buyer doesn't know where I live, can't scope my place out to burglarize while I'm gone at work.
I'm sorry for your loss... Here's hoping it doesn't happen again.
