On the other hand, it saw me, and explained to me that this--really, the section of front yard centered on the rangy little oak tree, including but not limited to the front sidewalk, the driveway, and the east side of the lawn, but specifically including the herb garden--was its territory, because it had a nest in said oak tree. It hovered around me in that "don't turn your back or you'll lose hair" sort of way, and squawked.
If it's going to claim ownership of a big chunk of property, maybe I can use this as some sort of tax write-off? I don't know.
My unsympathetic co-worker has suggested that I wear a hat with a big owl on it. Where to find one, though?
