Port Lockroy Gentoo Cove
Wiencke Island, Antarctic Peninsula (64.8°S) · Antarctica · polar
About this place
Study Pygoscelis papua 36 km/h hydrodynamic wing-propulsion, pebble-nest microtopography, and snow-highway energetics.
For kids: Meet the fastest underwater swimming birds on Earth, who propose with shiny smooth pebbles!

What to look for
- Snow-free pebble nest knoll — Pygoscelis papua thermal drainage nest. Locate the exposed dark bedrock knoll where pebble rings elevate eggs above meltwater
- Packed penguin snow highway — Communal snow-trench energetics. Centre the snow-slope corridor trampled into firm commuting trails
- Brash-ice krill harbour — 36 km/h underwater flight zone. Survey the sheltered channel where gentoos execute micro-bubble drag-reduction bursts

Ask together: Why would a pile of rocks make a much safer nest in melting summer snow than soft grass or feathers?
Field quiz
Kids' question: What secret trick helps penguins turbo-boost underwater right before jumping onto high ice?
- Squeezing tiny air bubbles out of their feathers like a fizzy rocket coat!
- Flapping their ears
- Pushing off whales
Answer
Squeezing tiny air bubbles out of their feathers like a fizzy rocket coat!
Adults' question: How does feather-trapped air assist diving penguins both thermally and hydrodynamically?
- Insulates skin during shallow dives and vents micro-bubbles to slash boundary-layer drag on ascent
- Inflates hollow wing bones for floating
- Provides oxygen directly into gill slits
- Produces ultrasonic krill-stunning pops
Answer
Insulates skin during shallow dives and vents micro-bubbles to slash boundary-layer drag on ascent
