In the hottest months of the year, Isla Martillo is the home of 2 species of penguins, Papúa and Magallánico. They come to reproduce, and the youngest ones to change their plumage. These young penguins are rather ugly and have missing feathers. The island is full of nests, which are holes in the sand surrounded by plants. I had never thought I could see so many penguins on a landscape like this.
