This is where spending some time to observe wildlife can really pay off. This looks like it might be a rare moment that likely took some split second shooting to acquire, when actually it was an event that was happening over and over again.
You see penguins like to walk in single file along a single path. There was a whole train of penguins dropping 1 by 1 off this ledge in order to get to the water to wash their dirty selves off and hunt for krill. The funny thing is every penguin in this train was filthy, having spent a shift incubating an egg or watching over their young in the nest while their significant other is out fishing. If I was to zoom out you would see a second stream of clean fat penguins toddling their way back up to the colony to feed their chicks and switch off with their partner. This is their life, they are living breathing animals and just like us they have relationships and work for a living, it's just that they get paid in krill.
