So, magpies understand that humans are inside their houses, when they go inside; on multiple ocasions I've had local magpies approach the window to peer inside - once craw outside an open door
I leave unsalted nuts for them on my balcony, I moved here recently, these are new magpies - I even managed to accidentally insult them, when they found my joint stubs and threw them all over the floor, in a fury, after I had used a similar plate to offer unsalted nuts
I now offer unsalted cashews on a plate *underneath* a lawn chair, to hide it from the gulls. The magpies have come to understand I am inside this building, and I offer cashews on an irregular basis, they sometimes hang out and just chitter, keeping the gulls from nesting
Unbothered by all of this is a nest of great tits, inside one of my vents, right behind me, they are very active in the early day, but remain completely silent for the rest.
I have not yet *met* my new local magpies, unlike the previous, which I was well aquainted with (one even tried to save me from a lounging, peaceful cat) - but they have shown an increased interest in my livingroom windows - they understand I lurk inside.
The great tits also happen to be generational nesters, btw - and have burrowed a hole in the fine grid wire plating, supposed to keep such out, probably many years and great tit generations ago
