Dead Birds

I work in a moderately tall building for the area it is in. Eight stories high but set in a residential area but also facing a vast empty lot that borders a highway. I am one of those lucky enough to have a cubicle next to a window and am able to see the sun and clouds and constant coming and going of cars in the parking lot. Because the building is in a residential neighborhood there are many trees with many birds living among them. The birds see to be extremely attracted to the windows in my building because every day I hear them crashing into the floors above and below me. Once in awhile I even see they hit near me. This is a perfect symbol for my existence in this building.
