Raptor Pee

After dinner we were walking back towards my apartment building when, circling overhead we saw a small bird of prey. I really need to start learning whats what so I can identify these critters but from here on in it shall be referred to as 'the raptor'.
The raptor settled on a building adjacent to mine, which my building overlooked. As I live on the top floor of the 12 floor building I decided to stick my head out the window and see if I could catch another glimpse of it. Well I was scanning the neighbouring building for any bird forms. Some way off there was a magpie on a rooftop, but my raptor, it appeared, was gone. Dejected, I hung my head and there, perched on the open window 4 floors below was the raptor. Excited about being so close and the unique perspective I rushed to my apartment, hastily attached lens to body and rushed back to the window.
Alas the perch was bare. I gave the surrounding windows another looking at before once again hanging my head. On the roof of the building next to mine, quite far down, there was a woman with two dogs, so I watched them for a little while. Then something moved from within the eighth floor. It was wing. The raptor was in the building.
Figuring that waiting for the elevator would take too long, barefooted I dashed down the stairs. I reached the eighth floor and tentatively poked my head around the corner. Sure enough, inside my apartment was this gorgeous bird of prey. I gingerly eased my camera to eye level and managed to just snap off one frame before the decided that it no longer wanted to be there and slipped out the window.
Hoping to get some shots of it gliding through the evening sky I dashed to the window, It was when I reached the window that I stepped in a puddle. A puddle that was directly under where the raptor had just been perched. I didn't managed to get anymore shots of it, but such a close encounter with an animal such as that was a great experience for me.
