A friend years ago had a magpie called Maggot! he was amazing, he lived in a aviary with a load of rescued pigeons but he used to bully them and peck out all their feathers, when one of the pigeons laid eggs and Maggots ate them my friend moved him to a different aviary on his own which he unfortunately escaped from and no-one could catch him, he hung around for a whole year, he would fly down and eat from the dogs dishes.
This was a working kennels and part-time rescue centre for waifs and strays and Denise would call "Dinner Time" every night when she went out to feed the dogs in their various runs. Maggot had learned to say this plus a couple of swear words.
He would sit in the tree and say Dinner Time when he saw us preparing the dogs food in the feed shed.
He eventually just disappeared, we think the fairer sex appealed to him more, I often used to wonder if he sat in trees calling dinner time to unsuspecting members of the public
