South Georgia, Subantarctic

This scene is an original illustration set in South Georgia, Subantarctic. It lies in mid-latitudes, where the climate is tundra — too cold for trees.

A dense colony of king penguins covers a shingle beach, each bird carrying orange ear and chest patches. Mounded tussock-grass slopes rise at the beach edges, and cold surf breaks beyond. Bare hills stand behind under a bright but cold midsummer sky.

Why do penguin colonies pack this densely?

Colonies this dense form where the sea offshore is extraordinarily productive and the land offers no ground predators — an isolated island near a zone of cold upwelling. Tussock grows in mounds because the ground is waterlogged and the growing season short. Bare rock above the tussock line marks where wind and cold stop plants altogether.
