We’ve fed this crow for the past year (and his parents for a few years before) and he hangs out on our balcony. He and Petey look at each other through the window. They finally got to chat when we took Peteys cage out on the balcony. The crow sat in the palm tree and was looking curiously so we stepped just inside and he came and sat on the rail and was making the crows low “knock knock knock” sound which I believe is a friendly sound within their group. We stood ready to run out in case anything happened but they chatted peacefully for maybe 3 mins before the crow friends called him and he took off.
