This 16 December 2019 video says about itself:
Gentoo Penguins Build Love Nests! | Penguin Post Office | BBC Earth
Why have a rock on your finger when you can have them in a nice neat pile? These Gentoo penguins have the right idea.
On a tiny island in Antarctica, there’s a post office surrounded by jaw-dropping scenery and 4,000 Gentoo penguins… Every summer, as tourists turn up in their hundreds to see the penguins and to send a postcard, the birds rush to find a partner and raise their young. This extraordinary four-month drama starts when the first penguin hops onto the island and continues until the last one leaves and the post office closes its doors for winter.
I was privileged to see these Port Lockroy penguins.
