Gentoo Penguin chicks hatch in structures that don’t look much like nests at all. Called scrapes because of their simple construction, the so-called nests of Gentoo Penguins are as elaborate as the Antarctic landscape allows. The breeding pair builds a small fortress of rocks and lines it with feathers and moss before laying eggs. The rocks that make up the nest are defended fiercely from colony neighbors during the breeding season. Noisy skirmishes break out when the ownership of particular stones is under dispute. Chicks are fed in the nest for about a month and then head off to sea.
