Magpies and Currawongs hold "court" and shun members who don't conform to local rules. And, administer punishment in exemplary fashion in front of the community.

Damn, that might be more than I can.

My mother feeds the local magpies, who turn up every morning for their free feed. One can argue about whether this is environmentally sound, but my mother lives alone and she enjoys the connection. She has them literally eating out of her hand.

This week she sent me a photo of a young juvenile magpie which had arrived for the first time, clearly brought along by the parents to learn the ropes.

I know an older lady who does this too, she just grabs beef mince from the fridge and feeds them every day. That probably isn't too harmful for them, at least it's not bread.

My grandma does the same thing. She'll come out and withold the food until it sings

Not just true of crows. I volunteer at a raptor conservation organisation in the UK. Many of the birds (eagles, vultures, owls, etc) recognise several people, especially those that fed them when they were being trained. They demonstrate this in the free-flying displays (where they could in principle just fly off if they wanted to) by routinely returning to the keeper, sometimes after flights where they travel some distance from the display area. They are also good at recognising and responding to signals, especially those that indicate a food treat may be forthcoming. In some cases the birds dislike specific individuals and will not work with them in a display.
