The main draw to Slimbridge is the duck and geese population, but I ended up focusing on herons.
It was unusual to see them so tame. These birds are usually wary of humans since, because of the damage they do to fish stocks, they are targeted.
But the herons at Slimbridge clearly feel safe and were readily approachable.

'Welcoming the public?' No, actually it's flexing its beak in preperation for spearing a fish.
