Every summer our Humboldt Penguins go through their annual moult. This moult is catastrophic ~ the birds lose all their feathers before growing a completely new plumage.

Immediately prior to the moult the penguins gorge themselves on fish instinctively knowing they are about to lose their waterproof covering for a few weeks.

After gorging the penguins swell up - including their flippers. At the Park this results in the keepers needing to cut off their identification tags to allow for expansion before replacing them once their flippers have returned to normal!
