SIGHTING REPORT UFO sighting at In the sky over Wakefield

Appeared to be the size of a whale, was a solid mass, long and seemed to have about 4 lights (yet not lights - but small highlighted areas underneath). The sky was black and so was the object and I could only make out the outline of its shape.

I was alerted to something strange first by the noise of what seemed to be the quacking sound of a duck which was strange in a residential area so I looked around to see what it could be. It was this noise that made me look up to the sky and could just make out a shape gliding through the air - constantly making this sound. It glided away making the same sound as it went.

I was able to follow the object by the sound and the highlighted features underneath. I was left thinking that this was more a strange durassic type creature than anything from outer space. My lasting impression was that it was like a huge mammal gliding through the air constantly making the sound of a duck but I could see no wings, however it was dark and as I said above, it was the outline only that I saw of a very large solid shape. I have no interest in UFOs and have never witnessed anything strange or unexplainable before.
