Owl in the hood

Early Sunday morning, a Great Horned Owl woke me up as it called from down the street. As I lay in bed, I saw it's shadow flash past my window, then it called from the other end of the street. I went downstairs and as I opened the door, it called from directly overhead. It must have been perched on top of our row house. When I stepped off the porch to look for it, I didn't see anything. I must have scared it off, as it called again but way off in the distance. I live on a block of row homes, a block from a park with narrow woods along a creek. Not what you would normally consider prime Great Horned Owl habitat, but you never know. Sometimes owls come to call, even in the most built up of neighborhoods.
