There are usually a few wild swans in Kent and in a group on Walland Marsh yesterday there were nine Bewick's, and five Whoopers grazing with around 30 Mutes. At one point one of each species were together. The left one is a Whooper, as big as a Mute, with the yellow on the bill going a long way down and finishing in a point. The Bewick's, is at the front, it is about 10% smaller with a smaller amount of yellow in the bill which in in a curve, behind is the Mute Swan. They were quite a long way away on a rather gloomy afternoon, so not the best photos, but they do show the differences quite well.
