Just made friends with a new resident magpie. Gave it a little mince (cooked from frozen with food grade calcium carbonate) as a once off bribe. I think it worked.

Flew off to its nest (you could here the little ones squawking nearby). Flew back realised it wasn't getting any more and just waddled around pecking at bugs right near my feet.

Eyeballs and scalp are safe for now.
