Yes, I must agree the first pic is definately a seagull, I was looking at it wrong, I do see it now. The ufo watch dog analasys is what threw me I think. It looked like what is actually the body and tail to be part of the wing. xeroxed88 posted a better diagram with a photo of the same type of gull. Like one of those optical illusion things once you look at it one way it's difficult to see it another way.
As for the other two I'm not sure.
