The Rockhopper Penguins form colonies of up to 100,000 in the Antarctic summer when they come ashore to lay eggs and raise their chicks.
"Along the main route between the penguin colony and the sea is this fresh water spring with a small waterfall," said Will.
This was an irresistible attraction for the penguins and throughout the day it was busy with squawking, squabbling, splashing birds.
