At first glance looking at a raft of ducks they might all appear the same. However there can be a wide variation and subtle differences between Mallards - one of the most successful species on the Planet.
They can vary in size, colour, feather patterns and shading. We have a few variations on the river. One of them I call the "Minister" due to the wide white band around his neck.
He has recently paired up with a rather light shaded female. It will be interesting to see if she produces any light variety ducklings next season. He has white tipped wings and more white underneath than the usual Mallard drakes.
The bill colour too is often quite varied, as some of the photos show.
