That’s cool, that he comes towards you. Does he already know you? Because last time I tried to feed unknown crows and they noticed me looking at them for two seconds, they got scared, even though I was like 10 meters away and other people had been passing closer than me. You could almost see a small exclamation mark above their head before they flew off. I still left some food and they came back to it, once I was further away.
Cool! I hope to befriend some crows someday.
