My history with corvids (crows, ravens, magpies) goes back a ways. When I was about 14 yrs old, I had my bedroom upstairs in an old farmhouse. There was a small window in a dormer and it lead right out onto the roof. My brother and I used to get onto the roof so we could see to the back of the property. On the prairies anything high will give you at least a 20-50km view. We weren't the only ones who used this 'perch'. A magpie discovered it while trying to amuse himself one day. He sat outside my window at about 4am and 'sang'. It was summer and it was hot so I had my window open. His raspy voice sent me flying outta bed. I flung open the screen and started swinging at him with my arms. He hopped out of the way and looked at me with great amusement. "Ach, ach, ach", he said and look for my response. I cussed him out with every word I knew and he responded, "Ach, ach, ach." I finally had to crawl out and chase him off. He visited me at 4 am for the next 4 days and sang before he lost interest and looked for someone else to pester.
