I can't decide if the pattern white stripes on the flanks shown in these photos show that there are four birds here, or can they vary substantially with, say, preening. I will keep an eye out at King's Dyke and see if any of these patterns repeat. If so, perhaps it will be possible to recognise individuals and make a more accurate assessment of how many birds are present at the site...

The shape, colouring and size of the beak is the only thing that should remain the same whatever Mike. Perhaps a closer examination of that may give you and idea.
