LOST BIRD, PLEASE HELP!

We have lost our beloved Mr. Nibbles. If you see him flying outside your window, please let me know. Or better yet, trap the little bugger. The kids are beside themselves with grief. They are crying and wailing and asking "when can we get a new pet? something other than a bird". We keep hearing him in the back yard, but he won't come down. I am hopeful that he will get hungry and want to come inside to the comfort of his birdie condo with deluxe heater and all the millet he can eat.
