California-based penguin photographer Ira Meyer reveals his favourite photos of the bird he's been documenting for more than a decade around Antarctica and the South Georgia region.
Over the years he has snapped a number of different species including Macaronis and Chinstraps. He says that a penguin's behaviour changes each season but they always guarantee to be entertaining.
