Gentoo Penguins, Saunders Island, Falkland IslandsThese two gentoo penguins really seemed like they were on some sort of top secret recognizance mission. I watched as they worked their way across the beach, past the dunes, into the hinterland where they forded a few shallow streams, never breaking focus on the importance of their undertaking.
