The beach which had been empty during the day took on a whole different character as night fell. Thousands of gentoo penguins came in from the sea and gathered there before heading inland to their colony. All across the bay, penguins were leaping as they came in, bursting from the waves in huge groups and running up onto the sand. A full moon rose just as the sun set.
On a little map of Bleaker Island that I had, a line between the beach and the penguin colony was marked as the "gentoo highway", which I thought sounded pretty funny. But actually it was a pretty accurate name - at rush hour on the gentoo highway there was a huge column of penguins all heading inland, waddling up the hill.
