I wondered what caused the sudden kerfuffle among the penguins. It was Against the Odds to be able to spot it, let alone get a mostly in focus picture.
There are always gulls around looking for a tasty snack. It must have been pretty tricky for them: the birds you see in the photo mostly have eggs tucked between their toes and a flap of tummy that spreads like a skirt impeding motion.
These were taken at Volunteer Point in the Falkland Islands.
