the hawk that attacked mine (which had a bad wing) from a very short distance out flew the hawk by weaving left to right, up & down. it was amazing to see, i was just so shocked, as the pigeons was on loft roof, then out of tree behind loft, flew the hawk, a maximum distance of 25 metres from loft roof to my back door, he grabbed a handfull of feathers, but to watch the pigeon dodge from left to right, up & under was now looking at it amazing, so it must be some kind of instinct.
