In the office hot. Snack at the open window into the yard, and there goes most important crow. She goes there the first day, because he knows - will give to eat. Looks at us, coming, jumps on the window sill and loudly screaming - screaming at us!
Give a piece of bacon. Crow moved away, biting, jumping back on the windowsill, yells, gets a piece of bacon. Partner offers her back later for dinner. Crow caws and flies away. And arriving for dinner ... again yelling at the window.
I suspect that she believes we are quite trainable, and even have some rudiments of reason ...
