Down with the tyranny of anti-bird spikes!

Birds, while pretty to look at, love pooping. Not only that, but they lack the tact and decency to do it somewhere out-of-view, instead pepping their white-and-black splats all over the sidewalk and whoever is unfortunate enough to be walking on it.

To counter this, some buildings have installed bird spikes, which prevent birds from landing (and shitting) on a ledge. Birds do not like this, and while most are dumb enough to simply take it, others, like this cockatoo, are smart enough to try to overthrow the system by taking them out.
