There is some great information here that we could all brush up on or if you ever need assistance with a stolen bird. Maybe one of the admins could sticky it? Bird Theft - Prevention and Crime Solving Assistance
Darlie thank you so much for posting that site. What good information! So scary to ever think of something like that happening. It dispelled a few ideas that I thought would make birds more secure, such as having dogs outside with them.
I sort of like letting people know I'd shoot someone trying to steal my birds and combine it with an alarm system. If you've got the cash get professional monitoring, if you don't, buy a sticker that says you do.
