By no means is this bird an actual "Ghost," but I have to admit that it was a BITCH to get a picture of.
See, I go up to my good friends' house every once in a while to hang out, mess with audio recording, and a lot of things of the sort, as well as visit a girl who is honestly the most impossible thing ever, and so over my stay I noticed a little something.
A "little" something it was, amongst running back and forth and inbetween, I kept noticing a little bird outside, and it was always in one of three plays, never saw it land there, never saw it fly away.
So in one particularly slow moment, I tried to get a picture of it, it was sitting on a little hanging planter outside, I look down for no less of a second to get my camera, look up, and it was gone.
Later on, it'd always do this, it'd just vanish and reappear in one of those spots, so it was my last day up there, and I saw it sitting there, and for once it just... oddly enough... sat there, and I got a million pictures of it, and I wasn't far away from it either. Then later on I even opened the door and took pictures, and it didn't move. Well, it didn't move until General (my friend's Great Dane) walked up behind me, then it was at the farthest part of the lawn on an old log.
General is a harmless 180 pound baby and just laid down beside where I was sitting and rested his head in my lap, but nevertheless, the most difficult critter I've ever taken a picture of, the bird that is.
