I used to work in an urban office building haunted by a pair of hawks. They would “attack” fifth floor conference rooms in the same manner if they felt threatened.
Steve Kane used to be a liberal.
The urban high-rise office building where I work has a problem with little birds flying into windows, not knowing anything is there. The birds crash into a window and the crash and the fall to the ground kills them. To fix this, building maintenance put up black silhouettes of birds on some of the windows - silhouettes of birds of prey like hawks - and this seems to scare the little birds away before they crash into the windows. I can’t say it works all the time but it seems to help.
