John was looking up now.
He couldn't quite process what it was he was looking up at. He stared for who knows how long, dumbfounded. The screaming noises of the pigeon became muffled as its head became engulfed and the frenzied screaming noises of one animal were replaced with the quieter, but no less disturbing, wet sucking sounds of the other's feeding. John suddenly wished that he had been thinking of anything else, anything other than animals having sex, on his way out the door. He did not want to ever have this image rush into his head in the future when he might start to think of ... DAMNIT! In hindsight the noise from out here had been nothing like...MOTHERFUCKER!
Blood was puddling below, no longer just splotching the white and black concrete. Most of the smaller pigeon had disapeared from sight. Tendrils from the thing's mouth were grasping and flailing messily at the remaining pieces.
A pigeon chunk fell loose and landed on John's face, startling him from his slack jawed silence.
