Gentoo Penguins are the fastest birds underwater, cutting through currents at an astonishing 36 km/h. That’s faster than Michael Phelps in full sprint mode, but there are no medals on the line for these guys, just catching fish and evading predators.
With their bright orange bills, white headbands, and curious personalities, Gentoos are often the penguins that approach you first on shore landings. They’re also the most widespread breeding penguin in the Antarctic region, popping up from the Falklands to the Antarctic Peninsula. Whether they’re porpoising through the water, fussing over pebble nests, or chasing each other along the beach, Gentoos make every encounter feel personal.
Like the other penguins in the region, you’re best chance at great viewing is from November to March, during the Antarctic summer, Gentoos are ashore breeding and raising chicks. This is when their colonies are busiest, with constant comings and goings as adults return from the sea with bellies full of food for their hungry young.
Again, like many other species of penguin, Gentoo pairs build circular nests out of stones, sticks, and vegetation. Males often present pebbles to females as part of courtship. They lay two eggs, and both parents share incubation and chick-rearing duties. Chicks fledge after about three months, joining the ocean as soon as they’re fully waterproof.
Gentoos combine striking looks with curious, approachable behaviour, making them a bit of a celebrity among expedition guides and their guests. Their agility in the water and quirky antics on land offer two very different but equally engaging wildlife experiences.
