Swans are very inquisitive and gentle creatures.  More often than not, when they see you, they’ll not hesitate in motoring up to see just exactly what you may have to offer.  In this case, this swan was very intent on coming over to check out if the camera I was holding was edible, to the point where he stood no more than 30cm from me sniffing around to see if I had anything of interest, before ripping out some grass from the ground.  Such a delight to be around.
