Cage bound parakeet

by Joel
(Leavenworth, KS United States)

My budgies fear the outside. I have had them for almost two years now and have got them to come onto my finger when asked, but they fly back in the cage when I try to get them out. My birds do not live in a small or round cage, there are places for them to retreat to, their cage is not suspended, and they seem to be really happy, yet they are still afraid. How do I help them overcome their fear of the outside?
