Min Ru Qiu, Immobilised forever (September theme: What Matters to Me )

On the first excursion of my trip to Antarctic, I saw this Gentoon penguin body lying on the snow. I only saw live Penguins through movie, Tv, book, and internet, but never saw a dead one before. As a doctor, I asked myself what it the cause of the death ? if this is a part of the penguin's life circle? or if this is related with human's activity ?
