"He became quite tame and his parents very quickly figured out where he was and would visit everyday and teach him how to be a magpie."
Piper's parental diet was supplemented with strips of lamb and it soon responded to Mr Webb's calls.
The growing magpie returned to his home at the macrocarpa trees, but Mr Webb continued to feed the bird.
However, last Tuesday, Mr Webb found Piper had injured his wing and was also limping.
He captured it and took it to the vet.
On return, Piper moved into a large dog crate and was carefully cared for by Mr Webb.
After six days, Piper was transported back to the trees.
But Mr Webb had not seen it since Monday morning -- and yesterday posted an ad on Trade Me in the hope of learning what had happened.
