It seems to happen rather frequently in bird-parks [or at least what I have seen] that around the time when the penguins are fed, there is often a heron lurking nearby so that they can get a free bite to eat..!
It's always entertaining to see
@dillotest0 The London herons are always there, not just at feeding times. The London penguins aren't very good at cleaning up after themselves and leave lots of fish everywhere .
