A few weeks ago, my co-workers and I were quietly going about our business as usual, when we heard a DWONG on the window. I looked over just in time to see a dark bird-sized blur fall out of sight. The bird left a small circle of minute feathers clinging to the outside of the window. We watched as they blew away.
A few days after that I went down and walked through the planter area to see if I could find the dead bird. Why? I have no idea. Mostly I wanted to know what kind it was, which is rather silly, as I can't identify many more types of birds than penguin, ostrich and flamingo. I looked around, at any rate, until I found the bird. It was a regular-looking birdish-sized grey-brown bird (can you tell I don't know my birds very well?) with a reddish-brown breast. I thought it had no head at first, but then I nudged it with my shoe and saw that the head had just been tucked underneath. I'm pretty sure it snapped its neck when it hit the window, then fell three stories to the ground, already dead.
