Picture me: sat on the sofa, opposite the French doors, vaguely paying attention to what was going on at the bird feeder, mildly amused by the extremely ungainly magpie.
The magpie that inspected the water bowl (that someone had thrown off its stand) and the feeder (that was empty) and the me (on the sofa) and Came To A Decision.
It did a tiny hop-skip-flap over and landed, very deliberately, on the workbench just the other side of the glass. It turned its head from side to side to get a good look at me from both eyes.
And then, having glared at me, it started yelling.
And kept yelling until I was up off the sofa and clearly heading for the door, whereupon it retreated to a safe distance, i.e. the garage rooves, and Continued Observing.
I sorted out the water dish. I got the crates of Misc Birdseed out of their cupboard. I sorted out the feeder. I sorted out the other feeder.
I went back inside.
Some time elapsed.
Eventually I got sufficiently puzzled about why the magpie hadn't come back yet to actually notice that I'd left the crates of seed out, and their cupboard door open.
I heaved myself back off the sofa.
I returned the seeds to their cupboard, and shut the cupboard's door. I returned myself to the sofa, shutting the patio door behind me.
Not terribly long after that, the magpie returned, and drank, and nibbled suspiciously (I had changed which food was in which feeder position), and appeared satisfied at least to the extent of not yelling any further...
... right up until the squirrel showed up to claim a portion of the restock.
I am absolutely delighted to have made this neighbour's acquaintance.
